Question

What would x equal for these equations of the triangle

Answer 1

x = 8

Explanation:

Given is an isosceles triangle.

Measures of two sides of an isosceles triangle are equal.

Therefore,

7x - 15 = 3x + 17

7x - 3x = 17 + 15

4x = 32

x = 32/4

x = 8

Answer 2

13.67

Explanation:

7x-15=58

7x= 73

x=10.42
