Answer:

Step-by-step explanation:

These are logically difficult, so it makes sense to me you're asking about this.

so A = 1/2 (big arc - small arc)

and 360 = big arc + small arc

then

360 - small arc = big arc

so rewrite the top equation

A = 1/2(360-small arc -small arc)

63 = 1/2( 360 - 2 small arc)

2* 63 = 360 - 2 small arc

126 = 360 - 2 small arc

2 small arc = 360-126

2small arc = 234

small arc = 234/2

small arc = 117

x = 117°
