Answer:
21.4
Step-by-step explanation:
We can solve for x using trigonometry
Here are the <u>Trigonometric Ratios</u>
Remember SOH CAH TOA
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
We are given the measure of ∠T ( 72° )
We are also given the adjacent side length (6.6) ( Adjacent = the side length that is not the hypotenuse nor the opposite side length )
And we need to find the hypotenuse ( longest side length )
We this information we can use the trigonometric ratio Cosine to solve for x
That being said we want to set up an equation
(remember cosine = adjacent over hypotenuse )

Now we solve for x
We can't get rid of the 6.6 itself so we want to multiply each side by x
now we have 
Step 2 divide each side by cos(72)

We're left with x = 21.35804865
Finally we want to round to the nearest tenth of a foot and we get that x = 21.4
The answer is b I hope this helps
Answer:
The inequality for w is 2
Answer:
If any of them are even correct, it'd be F.
The price is now 66 2/3% of what is was before.
Step-by-step explanation:
Given the stated equation we know that that quadratic formula has 2 as its degree. This meats it has 2 roots. A linear equation has a degree of 1. A linear equation has 1 root. To know if they intersect, the must have one root in common. To know this, solve the two equation simultaneously. If they result to an answer then they intersect.
