vocaloid · Answer

let the fourth angle = x

x = 360 - angle 1 - angle 2 - angle 3 
(the angles given in the problem)

anonymous · Answer

It wont let me do equal sign in the problem

vocaloid · Answer

then it's just 

360 - angle 1 - angle 2 - angle 3

anonymous · Answer

thats wrong

vocaloid · Answer

what did you put in as your answer? you might have messed up the signs somewhere

anonymous · Answer

360-angle 1- angle 2-angle 3

vocaloid · Answer

no, you need to put in the angles given in the problem

vocaloid · Answer

read the problem again

anonymous · Answer

i did that and it still said incorrect

vocaloid · Answer

no, what I mean was, you need to replace "angle 1" "angle 2" and "angle 3" with the angles given in the problem

vocaloid · Answer

60, −8y5, and +10y2 

^ these angles

vocaloid · Answer

make sure your signs are correct
