Question

I need to know how to do this?

Answer 1

since AOC is a straight angle then you know it's 180 degrees since AOC is consisted of BOC and AOB then BOC plus AOB =180

so 6x+29 + 3x+124 =180 solve and you get x=3

then plug in 3 to the BOC equation

6 (3) +29 which equals 47

your answer is 47
