Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:

Solving:
subtract 2x from both sides

add 11 to both sides

Next, find the angle measures of the two base angles:

To find y, you know that the interior angles of the whole triangle add up to 180, so you have

solving,

subtract 110 from both sides

divide both sides by 2
