Answer:
C
Step-by-step explanation:
Using the law of cosines then cosΘ is the following quotient
cosΘ =
where a = 5.8, b = 10.5 and c = 10.9
cosΘ =
=
= = 0.21 → C

Answer:
q = 3 + 1/2r
Step-by-step explanation:
10q - 5r = 30
We want to solve for q
Add 5r to each side
10q - 5r+5r = 30+5r
10q = 30+5r
Divide by 10
10q/10 = 30/10 +5r/10
q = 3 + 1/2r
