Question

In a triangle PQR, QR = PQ, measure of angle Q = 40 degree. The measure of angle P is:

1) 80 degree
2) 70 degree
3) 100 degree
4) 90 degree
​

Answer 1

Step-by-step explanation:

Given,

QR = PQ

so, ang P = ang R

let, the ang P nd R be 'x' degree

sum of all angles of triangle is 180 degree

Now, ang (P+Q+R) = 180

X + 40 + X = 180

2X = 180 - 40

X = 140/2 = 70

Hence, required angles are 70 , 40 nd 70.

AND MEASURE OF ANGLE P IS 70.
