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!

Answer:

x = 10.8

Step-by-step explanation:


\sf \sf cos(x)= (adjacent)/(hypotensue)

using cosine rule:


\rightarrow \sf cos(26)= (x)/(12)


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


\rightarrow \sf x =10.8
