Question

If angle P and angle Q are supplementary and the measure of angle P is 60°, then the measure of angle Q is *

Answer 1

Answer:

120⁰

Step-by-step explanation:

because the sum of supplementary angle is 180⁰

P+Q =180⁰. (P =60⁰) ( given)

60⁰+Q=180⁰

Q=180⁰-60⁰

Q=120⁰

Answer 2

Answer:

120°

Step-by-step explanation:

Supplementary angles are 180°

P = 60°

P + Q = 180°

∴ Q = 180 - 60

      = 120°
