1.	Two buildings on a plane ground are 30 m apart. From the top of the smaller building, one sees the base of the other building at an angle of depression of 60∘ and its top at an elevation of 35∘. The height of the bigger building is [Tan 60∘=1.7Tan 35∘=0.7] Let CD & AB be the smaller and taller building respectively. DE = AC = 30 m
Answer» Two buildings on a plane ground are 30 m apart. From the top of the smaller building, one sees the base of the other building at an angle of depression of $60^{\circ}$ and its top at an elevation of $35^{\circ} .$ The height of the bigger building is $[\begin{matrix} T a n 60^{\circ} = 1.7 T a n 35^{\circ} = 0.7 \end{matrix}]$ Let CD $&$ AB be the smaller and taller building respectively. DE = AC = 30 m

Answer»

Two buildings on a plane ground are 30 m apart. From the top of the smaller building, one sees the base of the other building at an angle of depression of $60^{\circ}$ and its top at an elevation of $35^{\circ} .$ The height of the bigger building is

$[\begin{matrix} T a n 60^{\circ} = 1.7 T a n 35^{\circ} = 0.7 \end{matrix}]$

Let CD $&$ AB be the smaller and taller building respectively.

DE = AC = 30 m
