Question

derive formula for height​

Answer 1

Answer:

Call the distance to the hill d.

Then tanB=hd and tanA=h+td.

Eliminating d gives the desired result:

htanB=h+ttanA

htanB=htanA+ttanA

ttanA=htanB−htanA

t=(tanA)(htanB−htanA)

t=h(tanA)(1tanB−1tanA)

t=h(tanAtanB−tanAtanA)

t=h(tanAtanB−1).
