3) A third staircase in a swimming pool has a landing of 15 inches and a vertical rise of 12 inches per step. To the nearest degree, calculate the following measures (you must show all work to receive full credit):

a) What is the angle of elevation rounded to the nearest whole degree?

b) If the elevation of each step were changed to 10 inches and the landing became 7 inches,

what is the new angle of elevation for the staircase to the nearest whole degree?

I've tried drawing a diagram and what I got to was tan x=12/15. I divided 12 into 15 to get 0.8 and I know there's a chart to see what degrees it is and I looked and there's too many degrees that start with 0.8 so I assumed I may have been wrong so am I or am I right which I bet I'm not since it was too easy
