## Homework Statement

A 1,000kg steel beam is supported by 2 ropes. What is the tension in each?

Rope 1 on the left is -20 degrees from vertical and rope 2 on the right is 30 degrees from vertical, making a V shape, the tops being connected to a ceiling.

## Homework Equations

Not sure other than converting kg's to Newtons at some point and probably using trig.

## The Attempt at a Solution

My friends and I think that the x components of both triangles formed have to add up to 0 and the y components of the 2 triangles need to add up to 1,000 kg.

rope 1=r1

rope 2=r2

(r2)sin30+(r1)sin20=0

(r2)cos30+(r1)cos20=1000kg

we tried solving for r1 in the first equation then substituting that into r1's spot in the second equation but that didn't work. any tips would be appreciated.. we've been trying to figure this out for the past hour
