1.find the measure of arc BEH
2.dind the measure of arc HE
3.find The measure of arc BCE
4.Find the measure of angle HBE

 1.  180°   2. 50°    3. 130°    4.  25°

Step-by-step explanation:

1 BEH is "intercepted" by the diameter,  therefore 180°

2 HE is the arc intercepted by the given central angle 50°

3 Subtract the given 50 from the 180  so 130

4.  Measure f Angle HBE  is 1/2 the intercepted arc HE, determined to be 50°

angle efh= angle egh

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
