so looking at the circle, you have an inscribed angle. which means the arc divided by 2 gets you the angle. but before you can even do that you need to find x. so you set all 3 equations equal to x like so: $x+15+3x+x+50=360$ then you work the problem out and you should get 59 once you have that it becomes a piece of cake. you insert x in the arc of ab so arc AB becomes $3\times59$ then once you have that you divide it by two to get the angle of ACB. which ends up being about 88.5
