Question

HELP I NEED THIS WITHIN 2 MINUTES AB if AC = 13.2 And BC = 6.8

Answer 1

Answer: 6.4

Explanation:

AB + BC = AC
AB + 6.8 = 13.2
AB = 13.2 - 6.8
AB = 6.4

Therefore, AB = 6.4

Answer 2

Answer:

AB = 6.4

Step-by-step explanation:

Assuming that AB + BC is AC, then we can say the following:

AB + BC = AC

AB + 6.8 = 13.2

AB + 6.8 + -6.8 = 13.2 + -6.8

AB = 6.4
