Answer:

m∠a = 97°

m∠b = 15°

m∠c = 68°

m∠d = 68°

Explanation:

Since WY and RZ are parallel lines and XR is a transverse,

m∠XWY = m∠XRZ

a = 97°

m∠WYX = 180° - 112° = 68°

In ΔXYW,

m∠WXY = 180° - (m∠XWY + m∠WYX)

= 180° - (a + 68°)

= 180 - (97 + 68)

= 180 - 165

= 15°

b = 15°

Since WY and RZ are the parallel lines and XZ is a transverse,

m∠WYX = m∠RZX = 68°

c = 68°

m∠d = m∠c [Alternate interior angles]

d = 68°
