Answer:
140°
Step-by-step explanation:
Given that angle a is 40 degrees, angle b = 140 degrees
because a triangle is half of a square
and a square is 360 degrees so a triangle is 180 degrees
so 180 - 40 = 140
Answer:
50 degrees
Step-by-step explanation: we know that
If two angles are complementary, then their sum is equal to 90 degrees so A+B=90° we have A=40° substitute and solve for B 40°+B=90° B=90°-40°=50°
