Given:
To find:
The value of "x" and "y".
Solution:
Let's solve "x" first.
Given is a supplementary angle so it should add up to 180°
Now, we can solve "y"
Given is an isosceles triangle so the opposite sides will be equal.
Angle sum of triangle is 180° so, it should add up to 180°
Therefore, the correct answer is option C
