Question 1039587: find the value of each variable the diagram show to rays that cross each other forming a large X on the left side angle is 3x+8 on the right side angle is 5x-20 and on the bottom angle is 5x+4y solve for X and Y Answer by josgarithmetic(39621) (Show Source):
You can put this solution on YOUR website! Vertical angles are congruent. Your "left" and "right" angles are of equal measure, so 5x-20=3x+8.
The sum of ALL FOUR angles is 360 degrees, so....,
but what you need next is that your "bottom" angle and your "right" OR "left" angle are supplementary, meaning their sum is 180 degrees. TWO of them; NOT the three of them.
Arbitrarily picking one, , and you would have already solved for x.
