Question

< used as the angle sign since i dont know how to do that on a computer, anyways

given: m<RST=2x+9, m<TSV=3x-2, m<RSV= 67 degrees

find x.

is the correct answer x=12?

anonymous · Answer

hmm... based on the given info, I got x = 57.2

anonymous · Answer

how did you solve it?

anonymous · Answer

when I sketched those angles out by their names, they made a complete full angle (360 degrees).
So 2x+9+3x-2+67=360 and solve to get x=57.2

anonymous · Answer

ohh.. so the whole angle equal 67 degrees. does that make a difference making the whole thing 360 degrees.

anonymous · Answer

It all depends on the letters they use. In this case RST, TSV, RSV, you may want to try sketching and you will notice they are referring to the 3 angles made at the same intersection of the 3 lines... hope that make sense... lol

lol ok yeahh it makes sense, i have the picture of it. ahhh im horrible with geometry! thanks for the help though!
