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
