X is 30+30=60 and Y is 180-(60+45)=180-105=75

@DenethVision123

x=60, y=75. is that correct?

@Mysteriousteacher2

Explanation                           First x + y + 45 = 180 (1) 
On side triangle two side is equal making it isoceleus triangle so let two = angle be theta ( t) so on 2nd triangle 2t+180- x = 180(2) 
Now 180 -x + t = 150 (3) 
By exterior angle is sum of remaining two angles after solving these three eq for three vareable 
X = 60
Y = 75 
t = 30

Can u explain too

@ManasjotSingh-c8x
