If y varies jointly as x and z. If y = 12 when x = 18 and z = 6, find y when x = 81 and z = 7.

If y varies inversely as x and y = 5 when x = 5, find y when x = 45.

If y varies directly as z and inversely as x and y = 27 and z = –3 when x = 2, find x when
y = 9 and z = 5.

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!
