A bullet was fired such that it just grazed the top of the table. It entered a wall, which was 12.60 ft from the graze point in the table, at a point 4.63ft above the tabletop. At what angle was the bullet fired above the horizontal?
.
Because the wall and the top of the table forms a angle of 90 degrees, you can apply trig.
.
tan x = opposite/adjacent
x = tan^(-1) (opposite/adjacent)
x = tan^(-1) (4.63/12.60)
x = tan^(-1) 0.36746
x = 20.2 degrees
