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.
