Question

the length of the base of an isosceles triangle is x. The length of a leg is 4x-5. The terminator of the triangle is 35. find x.

Answer 1

x= 5

Explanation:

We are given;

• Base of the triangle as x
• Length of the leg is 4x-5
• An isosceles triangle has two equal legs and a base.
• The perimeter of the triangle is 35 (spelling mistake in the question)

To get the perimeter of a triangle we add the lengths of all sides of the triangle.

Therefore;

x + 4x-5 + 4x-5 = 35

9x - 10 = 35

9x = 45

x = 5

Thus, the value of x is 5
