Answer:
x=50 and y= 20
Step-by-step explanation:
since it is a isosceles triangle angle B = angle C
so angle C and angle B add up-to 140 since angle A is 40
An B +an C=140
2x=140
x=70
in triangle BCD
an C = 70, and D =90, that means y will be 20
so y=20
from that we know that an B =70 means x+y =70
x+20=70
x=70-20
x=50
