Answer 1

Answer: 6*cot(50),  choice B

=====================================================

Explanation:

We're given an opposite side and an adjacent side. The tangent rule ties these two sides together. "tangent" is nowhere to be found in any of the answer choices, but cotangent is. Recall that

cot = 1/tan

which means

tan = opposite/adjacent

cot = adjacent/opposite

one is the reciprocal of the other

-----------

This means

cot(angle) = adjacent/opposite

cot(50) = x/6

6*cot(50) = x

x = 6*cot(50)

Answer 2

Answer:

The answer is option B

Step-by-step explanation:

To find the side adjacent to the 50° angle we use tan

$\tan( \alpha ) = \frac{opposite}{adjacent}$

From the question

The opposite is 6m

The adjacent is ?

So we have

$\tan(50) = \frac{6}{?}$

$? \tan(50) = 6$

$? = 6 \times \frac{1}{ \tan(50) }$

But

$\frac{1}{ \tan(x) } = \cot(x)$

So we have

$\frac{1}{ \tan(50) } = \cot(50)$

Substitute it into the expression

That's

We have the final answer as

$? = 6 \cot(50)$
