David drew triangle PQR as shown.

Question

.A triangle is shown with point Q at the lower left, point P at the top and point R to the upper right. Angle P measures 135 degrees.

If ∠QPR measures 135°, which statement is true for ∠PQR and ∠PRQ?

A. ∠PQR and ∠PRQ are right angles.
B. ∠PQR and ∠PRQ are obtuse angles.
C. The sum of the measures of ∠PQR and ∠PRQ is 45°.
D. The sum of the measures of ∠PQR and ∠PRQ is 135°.

Answer 1

well, the sum of angles P+Q+R = 180°, right?

Answer 2

P + (Q+R) = 180.
135 + (Q+R) = 180,
(Q+R) =

Answer 3

No
