To solve for x we have all the necessary numbers, because in an isosceles triangle two of the angles are equal. So the angles are 35*, 35*, and x* And since the interior angles of any given triangle will always equal 180* Then we know that x = 180-70 (35+35) or X = 110*
Use the same method for the other triangle and you’ll get Y = 49*
Sorry if my math is off a little. Hope this helps!
