Answer:

x = 140°

Explanation:

the secant- secant angle 10° is half the difference of the intercepted arcs

10° =
(1)/(2) (30 - ? )° ( multiply both sides by 2 to clear the fraction )

20° = 30 - ? ( subtract 30° from both sides )

- 10 = - ? ( multiply both sides by - 1 )

10° = ?

the lower arc is a semicircle = 180°

the sum of the arcs in a circle = 360° , then

x = 360° - 180° - 30° - 10° = 360° - 220° = 140°
