Answer:

AB = 8

Step-by-step explanation:

A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB

Step 1

Find x

BC = AB + AC

8x + 5 = 2x + 4 + 3x + 7

Collect like terms

8x - 2x - 3x = +4 + 7 - 5

3x = 6

x = 2

Step 2

Find AB

= AB= 2x + 4

AB = 2(2) + 4

AB = 4 + 4

AB = 8

SashulF [63]

We can Notice that ∠ABC = ∠ACB

We know that if Two Angles are Equal then Angles Corresponding to those Sides are also Equal.

⇒ AB = AC

⇒ 4x + 4 = 6x - 14

⇒ 6x - 4x = 4 + 14

⇒ 2x = 18

⇒ x = 9

⇒ Length of BC = 2x + 7 = 2(9) + 7 = 18 + 7 = 25 units
