### Example Question #1 : How To Find The Length Of The Side Of Of An Acute / Obtuse Isosceles Triangle

A triangle has a perimeter of inches with one side of length inches. If the remaining two sides have lengths in a ratio of , what is length of the shortest side of the triangle?

**Possible Answers:**

**Correct answer:**

Explanation:

The answer is .

Since we know that the permieter is inches and one side is inches, it can be determined that the remaining two sides must combine to be inches. The ratio of the remaining two sides is which means 3 parts : 4 parts or 7 parts combined. We can then set up the equation , and divide both sides by which means . The ratio of the remaining side lengths then becomes or . We now know the 3 side lengths are .

is the shortest side and thus the answer.
