Question

1 and 2 are a linear pair. m1 1= x - 30, and M2 = x+76 find the measure of each angle
<1= 67 <2 = 123
<1=37 <2 = 153
<1=37 <2 = 143
<1=67 <2 = 113

Answer 1

m 1 + m 2 = 180°
x - 30° + x + 76° = 180°
2 x + 46° = 180°
2 x = 180° - 46°
2 x = 134°
x = 134° : 2 = 67°
m 1 = 67° - 30° = 37°
m 2 = 67° + 76° = 143°
Answer:
C ) ∠ 1 = 37°, ∠ 2 = 143°
