Question

35. Find the measure of exterior <P of triangle
QRP, if the measurement of three interior angles
are <Q=75degrees,<R=50degrees <P=55degrees.​

Answer 1

Step-by-step explanation:

ANSWER

Complementary angles means when angles add up to 90 degree.

Since sum of a triangle is 180 degree, so if two angles angle P and angle Q are complementary then angle R will be 90 degree

∠P+∠Q+∠R= 180

90+∠R= 180

∠R= 90

Answer 2

Answer:

125°

Step-by-step explanation:

the measure of interior+exterior angles=180°

180-55=125°

so the exterior <P=125°
