An incleind palne rise a height of 2m over adistance of 6m the angle of slope

Answer 1

up 2 meters
now if the 6 meters is along the plane then
sin (angle) = 2/6 = 1/3
and angle = 19.5 degrees
however if the 6 meters is the horizontal distance under the plane then
tan (angle) = 2/6 = 1/3
and angle = 18.4 degrees
