Answer 3

use the formula -

external angle = (far arc - near arc) / 2

Answer 4

120-48 /2 :/

Answer 5

first figure out, what external angle, far arc, near arc are. then plugin

Answer 6

external angle - as the name says, angle outside the circle = 48

Answer 7

far arc - the arc that far away from the external angle = 120

Answer 8

near arc - the arc near to external angle = JK

Answer 9

external angle = (far arc - near arc) / 2

48 = (120-JK)/2

solve JK

Answer 10
