Answer:

B

Step-by-step explanation:

Since we know the measure of ∠B and the side opposite to ∠B and we want to find BC, which is adjacent to ∠B, we can use the tangent ratio. Recall that:

\displaystyle \tan\theta = \frac{\text{opposite}}{\text{adjacent}}

The angle is 54°, the opposite side measures 16 units, and the adjacent side is BC. Substitute:

\displaystyle \tan 54^\circ = \frac{16}{BC}

Solve for BC. We can take the reciprocal of both sides:

\displaystyle \frac{1}{\tan 54^\circ} = \frac{BC}{16}

Multiply:

\displaystyle BC = \frac{16}{\tan 54^\circ}

Use a calculator. Hence:

\displaystyle BC \approx 11 .62\text{ units}

BC measures approximately 11.62 units.

Our answer is B.

Miguel plans to paint a wood deck. He needs to buy the correct amount of paint. What is the area of the deck? If one can of pain
natali 33 [55]
Well, Miguel can paint infinite square feet if you do not give us the correct amounts. This is because we can assume that there are many buckets of paint.
