Question

Can someone help me answer question 1 & 2 on here?

Answer 1

1. 68, AB is Perpendicular to CB so ABC is 90°, the interior angles of any triangle equal 180 so, given CAB being 22°,

90+22=112,

180-112=68

ACB=68°

2. G=23°, Angle G is equal to 1/2 arc AD, so x+2=1\2(6x-80)

x+2=3x-40

2=2x-40

42=2x

x=21

plug it back in, so...

21+2=23

Angle G equals 23°
