Answer 1

Answer:

BC = 25

Step-by-step explanation:

AB = AC since it is an isosceles triangle

4x+1 = 2x+23

subtract 2x from each side

4x-2x+1 = 2x-2x+23

2x +1 = 23

subtract 1 from each side

2x+1 -1 = 23-1

2x = 22

divide by 2

2x/2 =22/2

x =11

BC = 3x-8

BC = 3(11) -8

BC =33-8

BC = 25
