Question

Find mZR in rhombus QRST.SR3w-440T

Answer 1

Opposite angles are equal:

3w-44 = m

The four interior angles of a rhombus add up to 360°.

w + (3w-44) + w + (3w-44) = 360

w + 3w - 44 + w + 3w - 44 = 360

w + 3w + w + 3 w - 44 - 44 = 360

8w - 88 = 360

8w = 360+88

8w = 448

w= 448/8

w= 56
