Let the angles be x and then solve by forming equations.
Though I have done. I recommend for rechecking the 2nd ans. Hope this helps you.

Answer:
Angle A = 60
Angle Q = 60
Step-by-step explanation:
In fig 1 let angle C = y
Therefore,
60 +3x + y = 180 ( Angle sum property of a triangle ) ------------ 1
in fig 2 let angle R = y
Therefore,
60 + 2x + 20 + y = 180 ( Angle sum property of a triangle ) -------- 2
In eq 1 and 2 , RHS is equal i.e., 180
therefore RHS is also equal
60 + 3x +y = 60 + 2x +20 + y
3x -2x + y - y = 60 + 20 + 60
x = 20
Angle A = 3x
= 60
Angle Q = 2x +20
= 40 + 20
= 60
