Answer:
X=24° Y=54°
Step-by-step explanation:
From the given hint, X-Y= -30...........(i)
Here ABC is a triangle.
So, A+B+C=180° ----Sum of all angles of
triangle is 180°
(2X+Y)+(Y-11)+(X+11)=180°
3X+2Y+11-11=180°
3X+2Y=180°..............................(ii)
Multiplying eq(i) by 2
2X-2Y = -60.............................(iii)
Adding eq (ii) and (iii)
5X=120°
X=24°
Putting X=24°in eq (i)
24-Y= -30
Y= -30-24
Y= -54°
