Question

Find X, BA, AC, and BC of isosceles triangle BAC.
BA= 2x-5; AC = 3x -9;
BC = X-2

Answer 1

BA = 3

AC = 3

BC = 2

x = 4

Explanation:

Find x

BA and CA are equal Given

2x - 5 = 3x - 9

Subtract 2x from both sides

- 5 = 3x - 2x - 9

- 5 = x - 9

Add 9 to both sides.

- 5 + 9 = x - 9 + 9

4 = x

=========================

BA = 2x - 5

BA = 2*4 - 5

BA = 3

AC = 3x - 9

AC = 3*4 - 9

AC = 12 - 9

AC = 3

BC = x - 2

BC = 4 - 2

BC = 2

Summary

• BA = 3
• AC = 3
• BC = 2
• x = 4
