Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
The answer is C because 90-55 is 35 and 90+55+35=180

hope I'm right and byee!! :)
Answer:
<u>A) 64.7</u>
Step-by-step explanation:
Taking the sine value of the given angle :
- sin 18° = 20/x
- 0.31 = 20/x
- x = 20/0.31
- x = <u>64.7</u> (nearest value)
Be more specific. Like what is it asking you to do ? I'm trying to help. :)
