To find the value of x where cos(22°), we can use the cosine function in trigonometry. The cosine of an angle in a right triangle is defined as the ratio of the length of the adjacent side to the hypotenuse. However, in this case, we are not provided with a specific diagram or lengths of sides, so we can directly evaluate cos(22°) using a calculator or reference table.
Calculating cos(22°) yields approximately 0.927. If we are to find the value of x rounded to the nearest tenth, we can express this as:
x ≈ 0.9
Therefore, the value of x rounded to the nearest tenth is 0.9.
