cos 58 = 8/x
To solve the equation cos 58 = 8/x, we need to isolate x.
We know that cos 58 = adjacent side / hypotenuse.
Let's assume that there is a right triangle where the angle opposite the adjacent side is 58 degrees. And let's label the adjacent side as 8 and the hypotenuse as x.
cos 58 = 8 / x
To isolate x, we can cross-multiply:
cos 58 * x = 8
Now, divide both sides of the equation by cos 58:
x = 8 / cos 58
Using a calculator:
x ≈ 16.6
Therefore, x is approximately equal to 16.6.
