Answer:

11

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that

... Cos = Adjacent/Hypotenuse

so you know ...

... cos(41°) = x / 14

Multiplying by 14 gives the value of x.

... x = 14·cos(41°) ≈ 10.566 ≈ 11

Answer:

11

Step-by-step explanation:

Here we are given a right angled triangle with a known angle of 41°, length of the hypotenuse to be 14 and we are to find the length of the base x.

For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.

[tex]cos \alpha =\frac{base}{hypotenuse}[/tex]

So putting in the given values to get:

[tex]cos 41=\frac{x}{14} \\\\x= cos 41*14\\\\x=10.56[/tex]

Therefore, the value of x is the closest to 11.
