The triangles are similar. Find x and y.
x = ___________
y = _________
△GHI is congruent to △JKL. Find the length of each side or the measure of each angle.
The easiest way for me to think of these is to find the scale factor.
Let the scale factor from △DEF to △HJK be s . So....
5s = 8.75
s = 8.75/5
s = 1.75
So each side of △HJK is 1.75 times the corresponding side of △DEF .
x = 1.75 * 4 = 7
y = 1.75 * 8 = 14
△GHI is congruent to △JKL . So....
GH = JK = 25 in
GI = JL = 14 in
KL = HI = 26 in
∠J = 78°
∠K = 31°
∠I = 71°
