Step-by-step explanation:
ln triangle PQR angle p is 60° and angle Q is 70°
Then sum of all angles of a triangle is 180°
= 60+70+angle R=180
angle R=50°
then MPR is exterior angle of triangle PQR
so by exterior angle theorem
angle MPR = angle Q + angle R
angle MPR = 50 + 70
angle MPR = 120°
in triangle MPR
MP=PR (given)
therefore triangle MPR is isosceles triangle
therefore angle PMR = PRM
angle MPR + angle PMR +angle PRM = 180°
120° + angle PMR + angle PMR = 180°
therefore, 2×angle PMR=180-120
angle PMR=60°÷2
therefore, angle PMR is 30°
so, angle QMR IS 30°
