Question

Find the value of x. Round to the nearest tenth. I’m going to Mcshoot myself pls help

Answer 1

Answer:

x = 10.8

Explanation:

$\sf \sf cos(x)= \dfrac{adjacent}{hypotensue}$

using cosine rule:

$\rightarrow \sf cos(26)= \dfrac{x}{12}$

$\rightarrow \sf x = cos(26) *12$

$\rightarrow \sf x =10.8$

Answer 2

Answer:

The answer is rounded 10.8

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse, or a/h. So, cos 26=x/12. To solve for x, isolation of the variable is necessary. If both sides are multiplied by 12, the equation becomes 12 (cos 26)=x. The cosine of 26 is 0.8988, which multiplied by 12 is 10.8.

Hope this helps!
