Question

△ABC△ABC is similar to △XYZ△XYZ.

Answer 1

Yo, im doing the same CR right now. haha
I think i have an idea on what to do. 
triangles have to equal 180 degrees. 
if A = 45
and C = 60
then B = 75
45 + 60 + 75 = 180.

it says the ABC is SIMILAR to XYZ. 
I think they are both congruent, so ABC and XYZ have the same measurements. 
that means is B = 75
then Y = 75.

i could be wrong, but thats what i think the answer would be.
