11/2 / 3 = 11/6 pounds per friend
divide 11/2 pounds by 3 in order to get answer
<u>Answer:</u>
The correct answer option is c. a = 11.94.
<u>Step-by-step explanation:</u>
We are given a right angles triangle with an angle ABC equal to 58 degrees and side length AC known to be equal to 19.1.
We are supposed to find the length of side a.
Side AC, opposite to angle ABC, will be the perpendicular and BC will be the base so we will use the formula of tan to find b.



Answer:
2.25 radians
Step-by-step explanation:
First we need to find the length of the circunference, using the formula:
C = 2 * pi * r
Where r is the radius. Using r = 8, we have:
C = 2 * pi * 8 = 50.2655 cm
Now, to find the measure of the central angle related to that arc of 18 cm, we can use a rule of three, knowing that the whole circunference has a central angle of 2pi radians:
2pi rad -> 50.2655 cm
x -> 18 cm
x = 18 * 2pi / 50.2655
x = 2.25 rad
