Question

Find the length of CB
.

Answer 1

CB = 7

Explanation:

CB = CK

5x - 3 = 3x + 1

5x - 3x = 1 + 3

2x = 4

x = 4 / 2

x = 2

CB = 5x - 3

= 5 ( 2 ) - 3

= 10 - 3

CB = 7

Answer 2

CB = 7

Explanation:

since the 2 triangles are AAS (B, K, E, CE as shared side) proven congruent, CB and CK must have the same length.

5x - 3 = 3x + 1

2x = 4

x = 2

CB = 5x - 3 = 5×2 - 3 = 10 - 3 = 7
