In ∆WXY, if WX ≅ WY , m∠W = x + 6, m∠X = 5x – 12, and m∠Y = 7x – 48, find x and the measure of each angle.

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Use the irregular polygon below. show all work. a. find the perimeter. b. find the area. the angles of the irregular polygon is 2, 8, 8, and 4.
