Question

Please help me with 7a

Answer 1

X and Y are the opposite given angles:

X = 45, Y = 30

Now look at the triangle made from A P and Z

Angle A = y = 30, Angle P = 30

The three inside angles of a triangle need to equal 180 degree, so Angle Z = 180 -30 - 30 = 120 degrees.

Z and W are vertical angles, which mean they are equal, so X also equals 120 degrees.

W = 120

X = 45

Y = 30
