Solve equations with complementary angles, practice answers, seventh grade

Answer 1

Sure! Here are some practice equations involving complementary angles:

1) Find the value of x:
40° + x° = 90°
x = 90° - 40°
x = 50°

2) Find the value of y:
y° + 20° = 90°
y = 90° - 20°
y = 70°

3) Find the value of z:
z° + 60° = 90°
z = 90° - 60°
z = 30°

4) Find the value of a:
a° + 70° = 90°
a = 90° - 70°
a = 20°

5) Find the value of b:
b° + 45° = 90°
b = 90° - 45°
b = 45°
