So this is like a pie chart or fractions
20 degreees is x% or x/whole parts
circle=360degrees
20/360=2/36=1/18

so the area represents 1/18 of the circle
684=1/18 of circle
multply both sdies by 18
12312=18/18 circle

the area of the circle=12312 yd^2

PLLLLLEEEAAAAASSSSEEE ANSWER NEED HELP!!!!!!!!!!!!!!!!!!!!!! WILL MARK 5 STARS!!!!!!!!!!!!!!!!
jek_recluse [69]

Answer:

UT = 8

Step-by-step explanation:

From the picture, we can make the following equation...

5 + 2x - 6 = x + 6

By solving it we get

5 + 2x - 6 = x + 6

2x - 1 = x + 6

2x = x + 7

x = 7

Therefor if UT = 2x - 6, then UT is equal to...

2x - 6 = UT

2(7) - 6 = UT

14 - 6 = UT

8 = UT

Half of the product of two consecutive numbers is 105. Which equation can be used to solve for n, the smaller of the two numbers
Illusion [34]
Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.
