## NCERT Solutions for Class 10 Maths Chapter 9 Some Applications of Trigonometry Exercise 9.1

### Question 1. A circus artist is climbing a 20 m long rope, which is tightly stretched and tied from the top of a vertical pole to the ground. Find the height of the pole, if the angle made by the rope with the ground level is 30Â° (see Fig.).

Solution:

In rt âˆ†ABC,

AB = pole = ?

AC = rope = 20m

sinÎ¸ =

sin30Â° =

AB = 1/2 * 20

AB = 10m

Height of pole = 10m

### Question 2. A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground making an angle 30Â° with it. The distance between the foot of the tree to the point where the top touches the ground is 8 m. Find the height of the tree.

= tan30Â°

= 1/âˆš3

AB = 8/âˆš3          -(1)

Now,

= cos30Â°

8/AC = âˆš3/2

âˆš3AC = 16

AC = 16/âˆš3           -(2)

From (1) and (2)

Height of tree = AB + AC

= 8/âˆš3 * 16âˆš3

= 8âˆš3 m

8 * 1.73 = 13.84m

The height of the tree is 13.84

### Question 3. A contractor plans to install two slides for the children to play in a park. For the children below the age of 5 years, she prefers to have a slide whose top is at a height of 1.5 m and is inclined at an angle of 30Â° to the ground, whereas for elder children, she wants to have a steep slide at a height of 3 m, and inclined at an angle of 60Â° to the ground. What should be the length of the slide in each case?

Solution:

In rt âˆ†ABC,

AB = 1.5m

AC = side = ?

= sin30Â°

1.5/AC = 1/2

AC = 1/5 * 2

AC = 3m

In rt âˆ†PQR,

PQ = 3m

PR = side = ?

= 2 * 1.73

= 3.46m

### Question 4. The angle of elevation of the top of a tower from a point on the ground, which is 30 m away from the foot of the tower, is 30Â°. Find the height of the tower.

Solution:

In rt âˆ†ABC,

AB = tower = ?

BC = 30m

= tan30Â°

AB/30 = 1/âˆš3

AB = 30/âˆš3

AB = 30/âˆš3 * âˆš3/âˆš3

= (30âˆš3)/3 = 10âˆš3

= 10 * 1.73

= 17.3m

The height of tower 17.3m

### Question 5. A kite is flying at a height of 60 m above the ground. The string attached to the kite is temporarily tied to a point on the ground. The inclination of the string with the ground is 60Â°. Find the length of the string, assuming that there is no slack in the string.

Solution:

In fig AB = AE – 1.5

= 30 – 1.5

= 28.5

In rt âˆ†ABD,

BC = 28.5/âˆš3          -(2)

CD = BD âˆ’ BC

= 28.5âˆš3 – 28.5/âˆš3

= 28.5(2/âˆš3)

57/âˆš3 * âˆš3/âˆš3 = (57âˆš3)/3 = 19âˆš3

19 * 1.73 = 32.87m

The boy walked 32.87m towards the building.

### Question 7. From a point on the ground, the angles of elevation of the bottom and the top of a transmission tower fixed at the top of a 20 m high building are 45Â° and 60Â° respectively. Find the height of the tower.

From (1)

1.6 + BC/âˆš3 = BC/1

âˆš3 BC = 1.6 + BC

1.732 BC – 1 BC = 1.6

0.732 * BC = 1.6

BC = 1.6/0.732

BC = 16/10 * 100/732 = 1600/732

BC = 2.18m

Height of pedestal is 2.18m

Let their height = h

Let DP = x

Then PB = BD – x

In rt. âˆ†CDP,

h/(80 – x) = 1/âˆš3

h = (80 – x)/âˆš3          -(2)

From (1) and (2)

(âˆš3 x)/1 = 80 – x/âˆš3

3x = 80 – x

3x + x = 80

4x = 80

X = 80/4

X = 20

Putting values of X in equation 1

h = âˆš3 x

h = âˆš3(20)

h = 1.732(20)

h = 34.640

Height of each pole = 34.64m

The point is 20m away from first pole and 60m away from second pole.

3x = x + 20

3x – x = 20

2x = 20

X = 20/2

X = 10

Width of the canal is 10m

Putting value of x in equation 1

h = âˆš3 x
