Question

find the measure of the unknown angle​

Answer 1

To find :- The value of X and Y

Angle opposite to equal side are equal ...

Therefore , X = 75 degree

By angle sum property

X + Y + 75 = 180 degree

X = 75 degree

75 + 75 + Y = 180

150 + Y = 180

Y = 180 - 150

Y = 30 degree

Therefore , X = 75 degree

Therefore , X = 75 degree Y = 30 Degree
