Question

Please solve this problem and find the value of x
​

Answer 1

x = 5

Explanation:

Since the base angles are congruent then the triangle is isosceles with the 2 legs being congruent, then

9x - 5 = 4x + 20 ( subtract 4x from both sides )

5x - 5 = 20 ( add 5 to both sides )

5x = 25 ( divide both sides by 5 )

x = 5
