Answer:

x =20 y=70

Step-by-step explanation:

40 is on a straight line so 180- 40=140

bottom half of the big triangleis isoscleles triangle so 140+2x=180

2x=40 so x=20

and then we know that the bottom side of 90 deg is 20

so the upper triangle is 70 deg where (90 was halved)

so we know that 70+40+y=180 because it is a triangle

so then y=70

we can prove this by doing 70+90+20=180 for the bigger triangle
