The values of x and BC are 9 and 25 units respectively.
The given triangle is an isosceles triangle with two equal sides. From the given triangle AB = BC
Since AB = 4x + 4 and AC = 6x - 14
Equating both sides
4x + 4 = 6x - 14
4x - 6x = -14 - 4
-2x = -18
x = 9
For length BC
BC = 2x + 7
BC = 2(9) + 7
BC = 25 units
Hence the values of x and BC are 9 and 25 units.
Question:
Find the value of x. Then find the length of the sides of given triangle.
