m<x= °
-45
-56
-63
-72

m<y= °
-45
-56
-63
-72

m<z= °
-45
-56
-63
-72

Answer 1

m∠x = 63°

m∠y = 45°

m∠z = 72°

Answer 2

ABCD is a parallelogram

opposite angles are equal

so

m<x= °<C = 63

Answer

63

---------------------------------------------

m<y = 180 - (72 + 63)

m<y = 180 - 135

m<y = 45

Answer

45

-------------------------------------------------

m<z= 72 (alternate interior angles are equal)
