Answer 1

Okay the answer is here

In the Triangle above

63° + 75 ° + x = 180
x = 180 - 138
x = 42°

Now as x is 42 so the angle horizontally opposite to it will also be equal

Hence the angle to the right side or the opposite side of x is also 42°

So it's very easy to get y

42° + 130 + 97 + y = 360
In the above quadrilateral

so y = 360 - 172 - 97
y = 91°


Hence the value of y in the figure is 91°

Hope it helps
