Answer:
The answer would be - BC is 25
Step-by-step explanation:
- Sides ab and ac are equal
- 4 x + 1 = 2x +23
- then after that you subtract 2 times from every side
- 2x + 1 = 23
- Then 1 more time from every side
- 2x =22
- Then divide by 2 on each side of the Triangle
- x =11
- BC = 3x -8
- After you do all of this then you would sub. the value of x
- So BC = 3*11 -> 33 -8
Answer:
BC=25
Step-by-step explanation:
this is an isosceles triangle, so sides AB and sides AC are equal
AB = AC
4x+1 = 2x+23
subtract 2x from each side
2x+1 = 23
subtract 1 from each side
2x =22
divide by 2 on each side
x =11
BC = 3x-8
substitute the value of x
BC = 3*11 -8
BC = 33 -8
BC=25
