Monique is using similar triangles in her graphic-design project. The triangles are isosceles. One has a base of 5 inches and legs of 7.5 inches. If the other triangle has a base of 14 inches, how long are the legs?
Since the triangles are similar, you can set up ratios of their corresponding sides.
solve for x
x/14 = 7.5/5
