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:
False
Step-by-step explanation:
The disjunction evaluates to ...
false or false
In order for an "or" statement to evaluate to True, at least one of the elements needs to be true. That is not the case here, so the disjunction is false.
Answer: x= 1, 
Step-by-step explanation:
The quadratic equation is
and
So we just need to sub in the proper numbers from the equation given, in this case, it would result in
and
Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1,
