Human body temperatures are normally distributed with a mean of 98.20 and a standard deviation of 0.62.
Find the body temperature corresponding to a z-score of z=1.73

Well, clearly whoever gave you this problem expects you to know that if x is from a normal distribution with mean $\mu$ and standard deviation $\sigma$ then the corresponding z, for the standard normal distribution, is given by
$$\frac{x- \mu}{\sigma}$$

Since here you are given z, put the given values into the equation and solve for x.
