156degrees , read from the 0 - line CB passes through the middle of 150, 160 but is just one notch beyond 155 therefore angle ABC is 156
If you struggle to just read that using the inner set of numbers, the angle on the other side of the BC line is 24 degrees (this should be easier to read as it's the outer numbers), so ABC is 180 - 24 = 156.
(can I hit frum the back now please?)
