Answer:
x = 76°
z = 14°
y = 42°
Step-by-step explanation:
48 + 2x = 180° because these three makes a straight line
2x = 180 - 48
2x = 132
x + z = 90° because these two angles are complementary angles since we know the value of x
76 + z = 90°
z = 90 - 76
48° + y = 90° because these two angles are complementary angles
y = 90 - 48
