Question

Using the polygon below, find the value of x and find the measure of Angle W. Enter the answer as a number.

Answer 1

x = 15

W = 30

Explanation:

There are 360 degrees in a rectangle. So the sum of all 4 angles should add up to 360. Use algebra to solve for x.

10x + 6x + 6x + (3x-15) = 360

25x - 15 = 360

25x = 375

x = 15

Plug in x = 15 to solve for W.

3(15) - 15 = 30
