My teacher is a dumbass and a horrible teacher. I swear he never taught us how to find tension and the "textbook" gives us long stories about little Billy and Bobby but never explains how to DO the problems. I need help for this question. Please explain if you can(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A street lamp weighs 150N. Its supported by two wires that form an angle of 120 degrees with each other. The tension in the wires are equal.

a) what is the tension in each wire supporting the street lamp?

b) If the angle between the wires is reduced to 90 degrees, what is the tension in each wire?

2. Formulas Needed

no clue. sorry

3. Attempts

I don't know any of this so I couldn't even attempt to do it. I don't know where to even start
