Ab And Bc Are Congruent Sides Of An Isosceles Triangle.If Ab=5x-2 And Bc=3xplus8 Find The Measure Of Congruent Side

ab and bc are congruent sides of an isosceles triangle.If ab=5x-2 and bc=3xplus8 find the measure of congruent side

 

Answer:

23 units

Step-by-step explanation:

Solve for x:

ab = bc

5x - 2 = 3x + 8

2x = 10

x = 5

Substitute:

ab = 5x - 2

ab = 5(5) - 2

ab = 25 - 2

ab = 23

ab = bc

23 = bc
