Answer:

x = 37 y = 65

Step-by-step explanation:

there are about 4 right angled triangles in the diagram

25 + 90 = 115

180 - 115 = 65

y = 65

53 + 90 = 143

180 - 143 = 37

the reason you add 90 is because the broken lines make right angled triangles for these isosceles

sum of angles in a triangle is 180
