Answer 4

hold on and i will do it then show you how

Answer 5

ok

Answer 6

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
