If the measure of ∠WYZ is four times the measure of ∠XYW, and the total of these angles is 180°, how do you find the measure of ∠WYZ?

Back

Let ∠XYW = x. Then ∠WYZ = 4x. Solve: x + 4x = 180° to find x, then calculate ∠WYZ.

Write the expression for the perimeter of a rectangle with length 4x - 8 and width x + 2.

Back

Perimeter = 2(4x - 8) + 2(x + 2)
