Can somebody plz help?e

Answer:

21.4

Step-by-step explanation:

We can solve for x using trigonometry

Here are the Trigonometric Ratios

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 )

$cos(72)=\frac{6.6}{x}$

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 $xcos(72)=6.6$

Step 2 divide each side by cos(72)

$\frac{xcos(72)}{cos(72)} =x\\\frac{6.6}{cos(72)} \\x=\frac{6.6}{cos(72)}\\cos(72)=0.3090169944\\\frac{6.6}{0.3090169944} =21.35804865\\$

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

Answer:

Step-by-step explanation:

There are FOUR equal sides so we eliminate some of the shapes that dont have equal sides.

We need a FOUR sided shape so we eliminate all the shapes that DONT have 4 sides.

We are now left with:

Square and rhombus.

Answer:

Step-by-step explanation:

(f - g)(x) = f(x) - g(x)

= $\frac{2x+6}{3x}$ - $\frac{\sqrt{x}-8 }{3x}$

Since both fractions have a common denominator of 3x, then subtract the numerators leaving the denominator, that is the numerators simplified

2x + 6 - ( $\sqrt{x}$ - 8)

= 2x + 6 - $\sqrt{x}$ + 8 = 2x - $\sqrt{x}$ + 14

Hence

f(x) - g(x)

= $\frac{2x-\sqrt{x}+14 }{3x}$ → A
