Answer:

x = 2

The smaller angle = 20

The larger angle = 70

Step-by-step explanation:

1/4 of a circle is 90 degrees

90 = 10x+ 20x+30

Combine like terms

90 = 30x+30

Subtract 30 from each side

90-30 = 30x+30-30

60 = 30x

Divide each side by 30

60/30 = 30x/30

2= x

10x = 10*2 = 20

20x+30 = 20*2 + 30 = 30+30 = 70

A circle has a radius of 12.6 cm.

d1i1m1o1n [39]

Circumference = 2 * PI * radius
circumference = 2 * PI * 12.6
If the central angle is 120°, then the arc will be exactly one third of the circumference.
arc length = (2 * PI * 12.6) / 3
arc length = 8.4 PI
