All sides of a triangle must add up to 180. 89 + 59 = 148. 180 - 148 = 32.
The first one (top left) is a function. Use the vertical line test, if a vertical line crosses the line drawn on the graph twice, then it's not a function.
Multiply eqn 1 by 3 and eqn 2 by 7 then adding them will cancel Y. and X can be found.
