a worker walked 8ft. upa ramp and was 3ft. above ground level. If he walkes an additional 12ft. up the ramp,how many ft. will he be from the ground?

• geometery -

one could say

8/3 = 12/height

h(8/3) = 12

h = (12x3)/8

h = 4.5

or use trigonometry and say

sinX= 3/8

X = (1/sin)3/8

X = 22.02 which is the angle of the incline

so

sin(22.02) = h/12

12sin(22.02) = 4.5
