Question

in the given figure, if the exterior angle is 135degree then angleP is​

Answer 1

Interior angle = 180 - Exterior angle
180 - 135 = 45
Therefore the E. Angle is 45 degree.

Answer 2

Step-by-step explanation:

Given PQ = PR. Then we know that if sides are equal then angles opposite to them are also equal.

So angle PRQ = angle PQR.

Let angle PRQ = x

then angle PQR = x.

We know that angle at a straight line is 180 degrees. Then

135+ angle PRQ = 180

135 + x = 180

x = 180 - 135

x = 45

So angle PQR = PRQ = x = 45

Then in triangle PQR, sumof all angles is 180

So angle P + angle Q + angle R = 180

Angle P + 45 + 45 = 180

Angle P + 90 = 180

Angle P = 90
