Angle opposite to the equal side of the triangle is always equal, it can be applied on the vice versa condition also. Thus, the length of BC is 17 units.

Given,

Angle B and angle C are marked congruent.

The length of the side AC is labeled as x plus 9.

The length of the side AB is labeled as 2 x minus 8.

The length of the side BC is labeled as x.

We know that the angle opposite to the equal side of the triangle is always equal, it can be applied on the vice versa condition also.

Therefore,

Angle B = Angle C

Thus,

AB = AC

2x - 8 = x + 9

x = 17.

The length of side BC is x.

Thus, the length of BC is 17 units.
