Question

If is an isosceles triangle, ​with base AC, AB = 3x+2, BC = 7x-6, and AC = 10x – 10, find the value of x and the length of each side of the triangle.

Answer 1

Explanation:

If is an isosceles triangle, ​with base AC, AB = 3x+2, BC = 7x-6, and AC = 10x – 10, find the value of x and the length of each side of the triangle.

The sum of angles in a triangle = 180°

AB + BC + AC = 180°

3x + 2 + 7x - 6 + 10x - 10 = 180°

20x -14 = 180°

20x = 180° + 14

20x = 194
