dfhfdhheeeeeey
is an angle bisector. WZX = 5x + 11, ZXW = 6x - 10, and XWZ = 91°. Find m<WXY
i'm confused can you draw a diagram ?
oh right sorrry! http://media.education2020.com/EVresources/647-05-01-00-00_files/i0090005.jpg
consider triangle WXZ ;- the 3 angles in your question are the 3 angles in this triangle., and they add up to 180 degrees so we can form the following equation which you can solve for x 5x + 11 + 6x - 10 + 91 = 180 then plug in this value of x itto the expression for angle WXY
Wait... I got 11+102=180 and then I subtracted 102 on both sides and i got 78... and divided 11 which gave me 7... but that's not my answer.
i mean the right answer.. the answer is 38, but i just don't know how they got 38.
