Question

An isosceles triangle has exactly two sides that are equal in length​ (congruent). If the base​ (the third​ side) measures 46 inches and the perimeter is 119 ​inches, find the length of the two congruent​ sides, called legs.

Answer 1

36.5 Inches

Explanation:

The perimeter of the triangle is the sum of all three(3) sides.

let the length of one congruent side be 'a', Therefore;

a + a + 46 = 119

2a = 119 - 46

a = 73/2

a = 36.5 inches.
