Find the value of x in the triangle shown below 3 6<br><br> 5<br><br> √18<br><br> √27<br><br> 4
Cerrena [4.2K]

a^2 + b^2 = c^2

In this case we're looking for C

so

(3)^2 +  b^2 = (6)^2

9 + b^2 = 36

b^2 = 36-9

√b^2 = √27

b = 3√3

Trig Help please! 50 points!
IgorLugansk [536]

Answer:

C

Step-by-step explanation:

Remember the mnemonic: SohCahToa, where:

\sin(\theta)=\text{opposite}/\text{hypotenuse}\\\cos(\theta)=\text{adjacent}/\text{hypotenuse}\\\tan(\theta)=\text{opposite}/\text{adjacent}

Let's determine our side lengths first.

Note that our angle is A. So, we have to determine the sides with respect to A.

The opposite side to A is 16.

The adjacent side is 12.

And the hypotenuse is 20.

With this, we can find our trig ratios:

Sine:

\sin(A)=\text{opp}/\text{hyp}

Substitute 16 for the opposite and 20 for the hypotenuse. This yields:

\sin(A)=16/20

Reduce:

\sin(A)=4/5

Cosine:

\cos(A)=\text{adj}/\text{hyp}

Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:

\cos(A)=12/20

Reduce:

\cos(A)=3/5

Tangent:

\tan(A)=\text{opp}/\text{adj}

Substitute 16 for the opposite and 12 for the adjacent. This yields:

\tan(A)=16/12

Reduce:

\tan(A)=4/3

So, our answers are:

\frac{4}{5}, \frac{3}{5}, \text{ and } \frac{4}{3}

Out of the answer choices, the choice that represents this is C.

So, our correct answer is C.

And we're done!
