SAT Question of the Day June 3rd 2013
In the triangles above,
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.
