How do I solve this using Sin or Cosine law?
Those two have both two formulas but when dealing with a not-right triangle which is a particular case you use this formula for sines.
[tex]\frac{SinC}{c} =\frac{SinR}{r}[/tex]
Substitute
Note: the capital letters are for the angles and the small letter are for the sides.
But since we used side R and there is no angle to substitute. you will basically have to find it by adding the two angles given and subtracting it by 180, which is a 100.
[tex]\frac{Sin(7)}{1.9} =\frac{Sin100}{x}[/tex]
now you do the butterfly method or cross multiplication method.
[tex]xsin(7)=1.9sin(100)[/tex]
You have to isolate the x
[tex]\frac{xsin(7)}{sin(7)} =\frac{1.9sin(100)}{sin(7)}[/tex]
now cancel and plug the right side of the equation into your calculator and u get the answer for the missing side.
[tex]x= 15.35[/tex] or if u want to round it [tex]15.4[/tex]
<R = 100 and side CK= 15.35 or 15.4

When surveyed, the ratio of students who preferred Science class to English class was 5:4. If 90 students were surveyed, how many students chose Science?
50 students preferred science...
Explanation:
we can consider the numbers 5 and 4 in the ratio as units
now we need to know how much each unit represent
units = 5 + 4 = 9
my sample = 90 students
each unit = 90/9 = 10 students
so each unit represents 10 students
back to the ratio
who preferred science = 5
who preferred English = 4
Number of students choose Science = 5 * 10 = 50

Vanessa uses the expressions (3x² + 5x + 10) and (x² – 3x - 1) to represent the length and width of her patio.
Which expression represents the area (w) of Vanessa's patio?

b) 3x4+14x³+22x²+25x-10
c) 3x4-4x³+22x²+35x+10
d) 3x1+14x³+28x²+35x+10
I’m not really the best at math, my apologies. Thank you.
Answer:
a) 3x⁴-4x³-8x²-35x-10
Step-by-step explanation:
3x2(x²-3x-1)+5x(x²-3x-1)+10(x²-3x-1)
3x⁴-9x³-3x²+5x³-15x²-5x+10x²-30x-10
3x⁴-9x³+5x³-3x²-15x²+10x²-5x-30x-10
3x⁴-4x³-8x²-35x-10
The expression 3x⁴ + 11x³ - 15x² - 40x - 10 represents the area (w) of Vanessa's patio
What is Expression?An expression is combination of variables, numbers and operators.
The area (w) of Vanessa's patio can be found by multiplying the length and width expressions:
w = (3x² + 5x + 10)(x² – 3x - 1)
Expanding this expression using the distributive property, we get:
w = 3x⁴ - 4x³ - 8x² + 15x³ - 25x² - 10x + 10x² - 30x - 10
Simplifying this expression, we get:
w = 3x⁴ + 11x³ - 15x² - 40x - 10
Hence, the expression 3x⁴ + 11x³ - 15x² - 40x - 10 represents the area (w) of Vanessa's patio

If x^2+y^2=13 and xy=6 then find the value of x^4+y^4
Recall that (a + b)² = a² + 2ab + b².
Let a = x² and b = y². Then
(x² + y²)² = (x²)² + 2x²y² + (y²)²

Given that x² + y² = 13 and xy = 6, we have
x⁴ + y⁴ = 13² - 2×6² = 97

The area of a 2D form is the amount of space within its perimeter. The correct option is D.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,
Area of L block = Area of A + Area of B
= (7×2) units² + (1 × 5) units²

1940 people attended a basketball game. 679 of the people attending supported the home team, while 1261 supported the visiting team. What percentage of people attending supported the home team?
Answer:
35%
Step-by-step explanation:
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The percentage of people who supported the home team is 35%.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
20% = 20/100 = 1/5
25% = 25/100 = 1/4
We have,
Number of people who attended the basketball game = 1940
Number of people who supported the home team = 679
Number of people who supported the visiting team = 1261
The percentage of people who supported the home team.
= [ Number of people who supported the home team / Total number of people who attended the basketball game ] x 100
= [679 / 1940] x 100
= 67900 / 1940
= 35%
Thus,
The percentage of people who supported the home team is 35%.

If the sales tax rate is 9.75 % in California, then how much would you pay in Los Angeles for a pair of shoes that cost $39.00?
Answer:
$42.80
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 9.75%/100 = 0.0975 per year.
Solving our equation:
A = 39(1 + (0.0975 × 1)) = 42.8025
A = $42.80
The total amount accrued, principal plus interest, from simple interest on a principal of $39.00 at a rate of 9.75% per year for 1 years is $42.80.
Answer:
Sales tax is $3.8. So total would be 39.00+3.8= $42.8

Answer:
7. 13.6
8. 19.5
9. 6.5
10. 12.6
Step-by-step explanation:
Recall the three main trig functions
Sine = opposite / hypotenuse
Cosine = adjacent / hypotenuse
Tangent = opposite / adjacent
( remember hypotenuse = longest side length , opposite = side length opposite of angle , and adjacent = side length thats not the opposite or hypotenuse )
We will use these to solve each problem
7.
We are given :
An angle with a measure of 39 degreesThe angles opposite side length The adjacent side as the unknownWhen dealing with opposite and adjacent we use tangent
We have tan = opp / adj
==> plug in opp = 11 and adj = x as well as given angle 39
tan(39) = 11/x
==> multiply both sides by x
xtan(39) = 11
divide both sides by tan(39)
x = 11/tan(39)
plugging this into a calculator , we get x = 13.6 ( rounded )
8.
We are given :
an angle with a measure of 46 degreesthe hypotenuse which has a length of 28and the adjacent as the unknownWhen dealing with adjacent and hypotenuse we use cos
We have cos = adj / hyp
==> plug in given angle 46 , adj = x and hyp = 28
cos(46) = x/28
==> multiply both sides by 28
x = 28cos(46)
plugging this into a calculator we get x = 19.5 ( rounded )
9.
We are given :
an angle with a measure of 51 degreesits opposite side length with a length of 8 the adjacent side length as the unknownWhen dealing with the opposite and adjacent we use tangent
We have tan = opp / adj
==> plug in 51 degrees for angle , opp = 8 and adj = x
tan(51) = 8/x
==> multiply both sides by x
xtan(51) = 8
==> divide both sides by tan(51)
x=8/tan51
plugging this into a calculator we get that x = 6.5 ( rounded )
10.
We are given:
an angle with a measure of 24 degreesthe hypotenuse which has a length of 31the side length opposite of given angle as the unknownWhen dealing with the opposite and hypotenuse we use sine
We have sin = opp / hyp
==> plug in angle as 24 , opp = x and hyp = 31
sin(24) = x / 31
==> multiply both sides by 31
31sin(24) = x
plugging this into a calculator we get that x = 12.6 ( rounded )
