Who trying to me w/ this pls i would be vv

For the first one, dab is 50 degrees and ac bisects it so angle a is 25 degrees. Then do 180-90-25 which is 65. 65 degrees is acb. Now look at the 180 degree line and subtract 180-65 which is 115. So measure BCE is 115 degrees.

For the second one, try it yourself. Just try to find all angles until you get the one you’re looking for

Set square i think so
