Why does a monkey have long arms?

Answer 1

to use them for geeting food and fhighting off preditors

That was someone else's answer. Fighting off predators? Not sure about that, but they have developed long arms to either walk on them or climb with them.

Answer 2

First of all Apes do not have tails.

Monkey: A lot of them use them as a prehensile 5th appendage to help keep their hands/arms free when in the trees eating or foraging. They also aid in balance..

Apes use a locomotion called brachiation, which means using the arms to swing around the branches. Presumably the tail would just get in the way of this mode of locomotion, so if one of the apes had a mutation that results in the loss of the tail, this one individual's descendants are more successful in survival and reproduction than the rest of the population with tails. Over time, only tail-less individuals can be found among the animals we call apes.
