In the triangles above, 3 times (y minus x) =

A.     15

B.     30

C.     45

D.     60

E.     105

The triangle on the left is an isosceles right triangle (two legs are equal and one angle is 90 degrees). This means X=45

The triangle on the right is equilateral – each angle is 60 degrees.

y-x=15 so 3(Y-X)=3 times 15 = 45

74% out of 160,000 got it right.
