Answer:
then what?
Step-by-step explanation:
do we have to find the angle?
all I know is every right triangle is equal to 90°
So, if we take 68.73 to be the 100%, what is 12 in percentage off of it?

seems Audryn is being generous, she probably got the silverware and the maple leaves tablecloth.
Answer:
(x - 3/4)^2 + (y - 1/2)^2 = r^2
<em>Brainliest, please!</em>
Step-by-step explanation:
Equation of a circle: (x - h)^2 + (y - k)^2 = r^2
(x - 3/4)^2 + (y - 1/2)^2 = r^2
We do not have enough information to find the radius. Were you given another point that lies on the circle?
Answer:
14
Step-by-step explanation:
Given that a package delivery company purchased 14 trucks at the same time. Five trucks were purchased from manufacturer A, four from manufacturer B, and five from manufacturer C. The cost of maintaining each truck was recorded.
No of companies = 3
No of items in total = 14
Total df = 17-1=16
degrees of freedom between groups = 3-1 =2
Hence degrees of freedom for denominator
=
Answer:
A
Step-by-step explanation:

as 0≤θ≤90
so θ/2 is also in 0≤θ≤90
hence sin θ/2 and cos θ/2 are positive.
