Answer:
117°
Step-by-step explanation:
The angle is obtuse, so thus greater than 90°. And the angles of a triangle must always add up to 180°, so 31 + 32 = 63, then 180 - 63 = 117°
Answer:
4 = 63
Step-by-step explanation:
angle 4 is the sum of 31+ 32 = 63
ALSO IS THE SUPPLEMENTARY OF ANGLE 3(117)
117+63=180
