To solve the expression where h8 is defined as h8 = 8 cos 8, we need to calculate the value of cos 8 first. The cosine function returns the ratio of the adjacent side to the hypotenuse in a right triangle, and its value ranges from -1 to 1.
Using a calculator or a cosine table, we find that cos(8) degrees (or radians, depending on the context) is approximately 0.9900. Now, substituting this value back into the equation:
h8 = 8 * 0.9900
Calculating this gives us:
h8 ≈ 7.92
Thus, the value of h8 is approximately 7.92.
