A 12ft ladder is resting against a wall and makes an angle of 52° with the ground. Find the height to which the ladder will reach on the wall.

length of ladder =  12 ft
angle with the ground =  52°
let h = height of ladder
thus
       sin 52° =  h/12          /  opp/hyp
         h=  12sin 52°
           =12*0.788 ~  9.456ft
