Answer 2

40 = 49 - 9

49 is equal to 7×7, or 7². 9 is equal to 3×3, or 3².

we can write this as [tex]7^{2}[/tex] - [tex]3^{2}[/tex]

Another way:

(10 - 3[tex])^{2}[/tex] - [tex]\sqrt{81}[/tex]

y=?​

Answers

Answer:

y = 2

x = 4

Step-by-step explanation:

The given is a special right triangle, the measure of its interior angles is as follows:

90-60-30 and side lengths would be:

2a - a[tex]\sqrt{3}[/tex] - a

as shown in image the side length that sees angle measure 60 is 2[tex]\sqrt{3}[/tex]

so the number represented by a is = 2 therefore y = 2 and x = 4

The sum of the interior angles of a polygon is 2700 degrees. Calculate the number of sides.

Answers

Answer:

17 sides

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here sum = 2700° , then

180°(n - 2) = 2700° ( divide both sides by 180° )

n - 2 = 15 ( add 2 to both sides )

n = 17

The polygon has 17 sides

Answers

Answer:

x=6

Step-by-step explanation:

Combine the equations and make them equal 180 because they make a linear angle. Simplify and solve. Good luck! 23×+3+6x+3=180

These two angles are supplementary. Since lines V and W are parallel, if we look at the corresponding angles for each given expression, we can see that they are congruent.

23x + 3 + 6x + 3 = 180

29x + 6 = 180

29x = 174

x = 6
