there are two triangles one leg is 160m in the first triangle. In the Second it is h. The hypothenus is 144. the other is 288. What is the h on the smaller triangle?

OpenStudy (anonymous):

Assuming similar triangles, set up a ratio

hero (hero):

Well, I realize that they are similar because they're apparently right triangles

OpenStudy (anonymous):

we are setting up a proportion

OpenStudy (anonymous):

yes they are right angles

OpenStudy (anonymous):

Not all right triangles are similar

OpenStudy (anonymous):

they are similar though in this problem

OpenStudy (anonymous):

Well the 160 belongs to the larger triangle, because the hypotenuse is the largest side of a triangle. \[\frac{288}{160}=\frac{144}{x}\]

OpenStudy (anonymous):

okay thanks for the proportion can help me solve it
