Question

solve que. 15 please give the answer.

Answer 1

given
angle q=60 deg.
means the given triangle is an equilateral triangle
so angle r = 60 degree
and angle p = 2x+20=60
so 2x=60-20
x=40/2
x= 20
HOPE IT HELPS

Answer 2

3x=2x+200(both triangles are congruent by SAS criterion)
3x-2x=20
therefore ,x= 20
