Question

What is the measure of arc c?
190
95
120
70

Answer 1

70°

Explanation:

By inscribed angle theorem:

`95° = (1)/(2)(c + 120°)\\\\</p><p>\therefore 95°* 2 = c + 120°\\\\</p><p>\therefore 190° = c + 120°\\\\</p><p>\therefore c = 190° - 120°\\\\</p><p>\huge \orange {\boxed {\therefore c = 70°}}`
