Answer:
- ∠H = 50°
- ∠A = 80°
- ∠W = 130°
Explanation:
It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.
∠A +∠K = 180°
8m° +10m° = 180°
18m = 180
m = 180/18 = 10
Using this value we can find ...
∠H = 5m° = 5·10° = 50°
∠A = 8m° = 8·10° = 80°
∠W = 180° -∠H = 180° -50° = 130°
