Ms.Henderson is using triangles in her graphic design project.The triangles are isosceles.One had a base of 4 inches and legs of 2 inches.If the other triangle has a base of 9 inches how long are the legs?
If the two triangles are similar you can use a proportion to solve for the length of the legs. [tex] \frac{2}{4} [/tex]=[tex] \frac{x}{9} [/tex] Now, you would cross multiply to get 4x=18 Now, you simplify that using the division property of equality. You end up with x=4.5 Therefore, the legs of the triangle with a base of 9 inches will each be 4.5 units long.
