Use pythagoras teorem
10^2 = 3^2 + x^2
x^2 = 100 - 9 = 91
x = 9.54 feet to nearest hundredth
Answer: 5%
Step-by-step explanation:
First notice that she contributes $300 a month and annually means yearly, so find the amount that she contributes yearly by multiplying 300 by 12 because there are 12 months in a year.
300 * 12 = 3600
Now to find the percentage, divide the amount she contributes in year by her annual salary.
3600/ 72000 = 0.05
Convert 0.05 into a percent by multiplying 0.05 by one hundred.
0.05 * 100 = 5%

Answer:
Answer: 64/3π -16/3)in²
Step-by-step explanation:
Area of segment equals area of sector minus area of isosceles triangle.
=0/360 x πr² -1/2r²sin (0)
Given; the length of chord, d=8√3in.
and the angle of the sector, 0=120
We can use the formula for calculating the length of a chord to find the radius of the circle.
D = 2r sin (0/2)
8√3= 2r (√3/2)
r=8in
Area of the segment= 120/360 x π x 8² - ½ x 8² sin (120)
= (64/3 π- 16 √3)in²
