Suppose you have a right triangle whose two short sides are of length $3$ and $4$ respectively. Then the smaller of the two acute angles is degrees and the larger acute angle is degrees. If you enter your angles as decimal approximations compute at least one digit beyond the decimal point.
Hint: Compute the length of the hypotenuse, use it to compute sines of the angles in question, and then apply the inverse sine function. Set your calculator to degree mode. If you use the ww asin function make sure you convert to degrees.
