Question

What is the measure of ∠PQR ? Enter your answer in the box. ° A triangle with one angle measuring 80 degrees and one angle measuring 70 degrees.

Answer 1

The answer is 30 degrees

Explanation:

(80+70) - 180 = 30

because all the angles should add up to 180 degrees so to double check your answer you do 30+70+80=180

Answer 2

∠PQR=30°

Explanation:

I assuming that the measure of angle PQR is the third internal angle of the triangle

Remember that

The sum of the internal angles of a triangle must be equal to 180 degrees

80°+70°+∠PQR=180°

150°+∠PQR=180°

∠PQR=180°-150°

∠PQR=30°
