Question

in triangle PQR, PQ =PR and angle Q = 50°, angle P = ?​

Answer 1

Answer:

P = 80°

Step-by-step explanation:

It is given that the triangle is an isosceles triangle then according to adjacent angle rule of isosceles triangle angle R = angle Q

Given -

Angle Q= 50° =angle R

acorrding to angle sum property of triangle

let angle p be x

angle P + angle R + angle Q = 180°

x + 50°+50° = 180°

x + 100° = 180°

x = (180 - 100)°

x = 80 °

therefore P= 80°
