correct, but x is only halfway up the cliff . . .
Tan35=x/120
x=120tan35
=84.02m
height of cliff=2*x
=2*84.02
=168.02m
x=120tan35
=84.02m
height of cliff=2*x
=2*84.02
=168.02m
Correct BT the work is nt too good

wrong
Angle of depression 35 degree height of cliff
Tan=opp/adj tan 35=120/x
X= tan 35*120=84.02cm
Tan=opp/adj tan 35=120/x
X= tan 35*120=84.02cm
