Answer:  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°
