Using the given information, we see that LOM + MON =LON. Now, we just substitute the expressions/numbers and simplify: (2x+33)+(3x+20)=113 2x+33+3x+20=113 Simplify 5x+53=113 Collect like terms 5x=60 Divide by 5 on both sides to isolate x x=12 Now we have found the value of x, we can find the value of MON. MON = 2x+33 MON = 2(12)+33 MON = 24+33 MON = 67°
