Question

The length of the base of an isosceles triangle is x. The length of a leg is 5x - 3. The perimeter of the triangle is 104.

Answer 1

Answer:

x = 10

Step-by-Step Explanation:

Since this triangle is an isosceles, that means two sides are the same and so being that two sides are the same, we can use this equation (5x - 3) • 2.

At first I tried 5, but soon after realized that it wouldn't be enough to make 104, so I doubled the number to 10.

x = 10

((5 • 10) - 3) • 2

(50 -3) • 2

47 • 2 = 94 ( sum of the two equal sides)

94 + 10 = 104
