how do I solve this?​

Answer:

z=7

Step-by-step explanation:

72°+(8z-8)°+(9z-3)°=180° (a triangle contains 180° and vertical angles are equal)

(8z-8)°+(9z-3)°=180°-72°

17z°-11°=108°

17z°=108°+11°

17z°=119°

z°=119°/17°

z°=7°

z=7

Answer:

The slope is 5/12

Step-by-step explanation:

To find the slope between any two points, we can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

We have the two points (-9, 1) and (3, 6).

Let’s let (-9, 1) be (x₁, y₁) and let (3, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-1}{3-(-9)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{5}{12}[/tex]

So, the slope of the line that contains the two points (-9, 1) and (3, 6) is 5/12.

Answer:

2x - 10 = 34 degrees

3x - 10 = 56 degrees

Step-by-step explanation:

Since they're complementary, they'd equal 90-degrees.

Solve for x:

2x - 10 + 3x - 10 = 90

5x -20 = 90

5x = 110

x = 22

2(22)-10 = 34

3(22)-10 = 56

Answer:

Johnny is wrong.

Step-by-step explanation:

To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.

If we choose to use milimeters, we have

600cm=600cm [tex]\frac{10mm}{1cm}[/tex]

600cm = (600)(10) mm

600cm = 6000 mm

Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.

In fact, 6000-5642 mm =358 mm would remain.

Answer:

110.5 cm²

Step-by-step explanation:

The figure is composed of a rectangle with a triangle on top.

Area of rectangle = 13 × 6 = 78 cm²

Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 13 and h = 11 - 6 = 5 cm , then

A = [tex]\frac{1}{2}[/tex] × 13 × 5 = 32.5 cm°

Thus

total area = 78 + 32.5 = 110.5 cm²

Answer:

Tan J = 0.2917

Step-by-step explanation:

Here, we want to find the value of tan J

Firstly, we need to understand that the numbers 24, 25 and 7 are a Pythagorean triple and as such the three measures represent the values of length of the sides of a right angled triangle

The tangent of an angle= measure of the opposite/measure of the adjacent

In the question, the opposite to point J measures 7 while the adjacent measures 24

So ;

tan J = 7/24

= 0.2917

Step-by-step explanation:

Gradient or slope = (7-6)/(4-(-8))

= 1/12

The gradient of a line is the same as the slope of the line.

The gradient of the line segment between the points (-8,6) and (4,7) is 1/12

The points are given as:

[tex](x,y) = \{(-8,6),(4,7)\}[/tex]

The gradient (m) of a line segment is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{7-6}{4-(-8)}[/tex]

[tex]m = \frac{7-6}{4+8}[/tex]

[tex]m = \frac{1}{12}[/tex]

Hence, the gradient of the line segment is 1/12

Answer:

C

Step-by-step explanation:

We know that line CD passes through the two points (0, 2) and (4, 6).

First and foremost, let’s find the slope of the line. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (0, 2) be (x₁, y₁) and (4, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-2}{4-0}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{4}{4}=1[/tex]

Hence, our slope is 1.

Now, we can use the slope-intercept form:

[tex]\displaystyle y=mx+b[/tex]

Where m is our slope and b is our y-intercept.

Notice from our given points that we are given (0, 2).

So, our y-intercept is 2.

Therefore, we will substitute 1 for m and 2 for b. This yields:

[tex]\displaystyle y=(1)x+(2)[/tex]

Simplify:

[tex]\displaystyle y=x+2[/tex]

Hence, our answer is C.
