Soln'n
let x=your distance from the foot of the monument.
128=height of buddah
25=height of pedestal
1.6 =your height
15=angle of elevation
∮=angle of elevation of ur eyes to the top of statue

sol'n
solve first the distance x
tan(15)=(25-1.6)/x
x=87.23

next, solve the angle ∮
tan∮=(153-1.6)/87.23
tan∮=1.7337
∮=arctan(1.7337)
∮=60.023 degrees
