Arc AD=90 acr BC = 86 find the value of FG

To find larger arc, add them = 176

Smaller arc, subtract = 4

Angle AD and Angle BC are equal to their arcs

Inscribed Angle of the entire arc, half of 176 = 88

Inscribed Angle of AD (90 degrees) = 45

Inscribed Angle of BC (86 degrees) = 43

Possible answers of FG * note all answers are in degrees
