Answer:
C = 21.78 and a= 8.88
Step-by-step explanation:
Here, sides b=7 and c=3
Also, Angle B=60
Angle B is between side c and a
It can be solve by cosine rule and sin rule
sin rule says,

cosine rule says,

Answer:
8 1/3 liters
Step-by-step explanation:
create a proportion from water : yard
let 'y' = water for entire yard
5/3 ÷ 1/5 = y ÷ 5/5
5/3 · 5/1 = y/1
25/3 = y/1
3y = 25
y = 8 1/3
Answer:
To find the value of this expression you need to add and subtract from left to right
74.9+5.23-81.4-16 (add the first two, first)
80.13-81.4-16 (74.9+5.23=80.13) (next subtract the next two)
-1.27-16 (80.13-81.4=-1.27) (Last subtract the last two)
-17.27 (-1.27-16=-17.27)
-17.27

1. Find the area of the circle. You know the radius = 10 in. Use

2. Find the area of the (I'm assuming) equilateral triangle. Use the 30-60-90 rule to determine the length of half one of the edges, since you already know the hypotenuse of the 30-60-90 triangle. Multiply that value by 2 to get the length of one side. Then use

to find the area, where l = length of one side.
3. Subtract the area of the equilateral triangle from the area of the circle to find the area of the shaded region.
