Question

Need help Finding the side length X.

Answer 1

Because the 2 triangles are similar, find the ratio of 2 known sides.

Side XY = 10

Side AB = 25

25 / 10 = 2.5

This means the larger triangle is 2.5 times larger than the smaller one.

Now find the side of the smaller triangle, that would be the same side as X on the larger triangle and multiply that by 2.5.

XZ is the same side as AC

So X = 6 x 2.5

X = 15
