point is B is on AC, what us the length of AB if AC=22 and BC=13? Please help me!, I'm falling in math class!!

den301095 [7]

Answer:

Step-by-step explanation:

There are two answers to this.

The order is ACB. That means that B is beyond C.

In which case AB = AC + BC

AB = 22 + 13

AB = 35

The order is ABC (which means that B is between A and C.

AB = AC - BC

AB = 22 - 13

AB = 9

Please don't ask me what the answer is. The question does not make it clear enough to give you one answer. I do suggest you draw a diagram to show both possibilities. Your teacher will likely applaud you for poking holes in the question.
