The sides of a triangle are in a ratio of 5:7:9. If the perimeter of the triangle is 147 inches. What is the length of the smallest side of the triangle.

The triangles are similar. what is the value of x? enter your answer in the box. x = two right triangles. the larger right triangle is labeled x on the longer leg, 12 on the shorter leg and 20 on the hypotenuse. the smaller triangle is labeled 4 on the longer leg, 3 on the shorter leg, and 5 on the hypotenuse.

Consider the diagram. which line segment has the same measure as st? rx tx sr xs
