In AQRS, the measure of _S=90°, SQ = 13 feet, and QR = 59 feet. Find the measure of ZR to the nearest tenth of a degree.

Carmen and matt are conducting different chemistry experiments in school. in both experiments, each student starts with an initial amount of water in a flask. they combine two chemicals which react to produce more water. carmen's experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second. matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second.
