Question

Find cos x if sin x cot x = 0.5.

Answer 1

Answer:

Choice A is correct.

Step-by-step explanation:

We have given that:

sin x cot x = 0.5.

We have to find the value of cos x .

As we know that cot x is the ratio of cos x and sin x.

cot x = cos x / sin x.

We have,

sin x (cos x / sin x) = 0.5.

cos x = 0.5

cos x = 0.5 is the answer.

Answer 2

Answer:

Choice A

Step-by-step explanation:

We are given;

$sinxcotx=0.5$

but we know that;

$cotx=\frac{1}{tanx}=\frac{cosx}{sinx}$

Substituting the last expression in place cot x yields;

$sinx*\frac{cosx}{sinx}=0.5\\ cosx=0.5$
