Answer:
B, 
Step-by-step explanation:
Using the law of cosines, which is 
, you can simply insert all the values.
c=|u+v|
a= r value of u (10)
b= r value of v (5)
To find C, you simply have to subtract v from u, and then subtract that number from 180 to find the reference angle.
I.E.: ∠135 - ∠30 = ∠105 ↔ 180 - 105 = 75 = C
so, the completed equation would be 10^{2} + 5^{2}- 2(10)(5)cos(75)
Answer: 1/4 pound(s) of candy in each bag

Answer:
the square root of 121 is 11
<span>slope formula, which states that m = (y2 -- y1) / (x2 -- x1).</span>
Answer:
y = -
x-7
Step-by-step explanation:
y=mx+b where m = the slope and b = the y intercept
the slope = change over y/change over x = (5-(-3))/(-9-(-3))=(5+3)/(-9+3)=8/(-6)=4/(-3)
y=-4/3x+b
plug in one of the points (it can be either)
-3=-4/3(-3)+b
-3=4+b
b=-7
y=-4/3x-7
