Answer:
75.52
Step-by-step explanation:
All you have to do is second cos, or cos^-1(2/8), because of sohcahtoa, adjacent hypotenuse, so it is cos.
I found the image that accompanied this problem.
We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
I'll help you get started, 'though I won't solve all these problems for you.
"What percent of 84 is 12?" Write the fraction 12/84 and then mult. the resulting decimal fraction by 100%:
0.1429(100%) = 14.29%
"What number is 35% of 72?"
Let the number be n. Then 0.35(72) = 25.2 (answer)
If you'll try some of the others and share your work, I'd be glad to comment on your efforts.
Answer:
<h2 />
Step-by-step ex
He shows the formula to find it which is 360/n, where n is the number of sides of the regular polygon. He goes on further to explain the formula by taking an 18-sided regular polygon as example and computes its exterior angle as 360/18, which is 20 degrees
Theirs alot of people in this world so watch out.
