Answer»

ong>Answer:

P = 90°

Step-by-step explanation:

Given: = 135°

PQ = PR

>angle PRQ + EXT. angle = 180° ( since it is a STRAIGHT line)

PRQ + 135° = 180°

PRQ = 180° - 135° = 45°

Now, angle Q = angle R = 45° (since PQ = PR)

THEREFORE,

>angle P + angle Q = ext. angle (since

ext. angle is equal to the SUM of interior opposite angles)

angle P + 45° = 135°

angle P = 135° - 45° = 90°
