Answer:

140°

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°
