Answer:
C. 6.736
Step-by-step explanation:
The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.
The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.
___
If you want to actually use the law of sines to determine x, you know that ...
x / sin(60°) = 5 / sin(40°)
x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)
x ≈ 6.736
Answer:
x=32
Step-by-step explanation:
x/2-7=9
1/2x-7=9
add seven to both sides
1/2x=16
multiple both sides by two
x=32

Answer:
2
inches
Step-by-step explanation:
First, I would try to get the mixed numbers into improper fractions. Then, I try to make them have the same denominator so it is easier.
1
feet --- 2 inches
feet --- 2 inches
feet --- 2 inches
1
feet --- ? inches
feet --- ? inches
feet ---
× 2 inches
= 2
inches
C=m/3.
