Question

What is the measure of angle D

Answer 1

Answer:

52 degrees

Step-by-step explanation:

A triangle's angles all add up to 180 degrees so we can create this equation:

x + 20 + 3x + 32 = 180

Combine like terms.

x + 3x + 20 + 32 = 180

4x + 52 = 180

Subtract 52 from both sides.

4x = 128

Divide.

128 / 4 = 32

x = 32

Plug in the value of x.

x + 20

32 + 20

52

Angle D is equal to 52 degrees.
