The problem is as follows: A mass is held by two cables attached to a wall and ceiling. The mass M is 5 kg and the angle between the string and the vertical is θ= 25°(adsbygoogle = window.adsbygoogle || []).push({});

a) Determine the tension in the cable attached to the ceiling.

I know that the answer is 55 N (because she posted the teacher posted the answers), and i know that the answer was derived by using the equation Ft= 50N/ Cos(25)

My question is why does the equation look like this when in other problems the answer comes from "magnitude of vector * desired trig function(θ)"

Bottom line: what key information tell me to put the newtons of force over the trig function?

PLEASE LEMME KNOW ASAP CUZ THE TEST IS TOMORROW!
