[4]2.A | Complete the following activities and rewrite it (any two)
[2]2.A.i

From the top of building AB, a point C is observed on the ground whose angle of depression is 60° and which is at a distance of 40 m from the base of the building. Complete the following activity to find the height of building AB.


From figure, BC = `square`, ∠ACB = `square`

In ΔACB,

tan `square = square/(BC)`

⇒ `square = square/square`

⇒ `square = square`

Hence, the height of the building AB is `square`.

Find the total surface area of frustum, if its radii are 15 cm and 7 cm. Also, the slant height of the frustum is 14 cm.

Radii of the frustum = `square` cm and `square` cm

Slant height of the frustum = `square` cm

Total surface area = `π[(r_1^2 + r_2^2 + (r_1 + r_2)l]`

= `22/7 [square + square + (square + square) square]`

= `22/7 (square)`

= `square` cm2

Hence, the total surface area of the frustum is `square`.

If the length of the diagonal of a cube is `5sqrt(3)` cm, find the total surface area.

Length of the diagonal of the cube = `square`

So, `square` = `5sqrt(3)`

⇒ Side = `square`

Total surface area of cube = `square`

= `square` × `square` × `square`

= `square` cm2

 Hence, the total surface area is `square`.

Determine whether the following points are collinear. A(–1, –1), B(0, 1), C(1, 3)

Given: Points A(–1, –1), B(0, 1) and C(1, 3)

Slope of line AB = `(square - square)/(square - square) = square/square` = 2

Slope of line BC = `(square - square)/(square - square) = square/square` = 2

Slope of line AB = Slope of line BC and B is the common point.

∴ Points A, B and C are collinear.

Prove that: cot θ + tan θ = cosec θ·sec θ

Proof: L.H.S. = cot θ + tan θ

= `square/square + square/square`  ......`[∵ cot θ = square/square, tan θ = square/square]`

= `(square + square)/(square xx square)`  .....`[∵ square + square = 1]`

= `1/(square xx square)`

= `1/square xx 1/square`

= cosec θ·sec θ  ......`[∵ "cosec"  θ = 1/square, sec θ = 1/square]`

= R.H.S.

∴ L.H.S. = R.H.S.

∴ cot θ + tan θ = cosec·sec θ
