Find each variable find x and y

x and y are equal b/c the triangle is isosceles triangle

when we see the angles of the triangle we get 2 equal angles

so to find the value of each variable we've subtract the parallel sides from the angles which means x=180°-45° y=180°-45°

x=75° y=75

b/c of it's isosceles triangle the two sides and angles are equal

d

gimmee one of those gold crowns!

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
