A ladder makes an angle of 60° with the ground when placed against a wall. If the foot of ladder is 2 m away from the wall, then the length of the ladder ( in metres) is
We are given: - The ladder makes an angle of 60° with the ground. - The distance from the foot of the ladder to the wall is 2 m. Using the cosine function: cosθ = (Adjacent side) / (Hypotenuse), where θ = 60°, Adjacent side = 2 m, and Hypotenuse = Length of the ladder (L). Substitute the values: cosRead more
We are given:
– The ladder makes an angle of 60° with the ground.
– The distance from the foot of the ladder to the wall is 2 m.
Using the cosine function:
cosθ = (Adjacent side) / (Hypotenuse),
where θ = 60°, Adjacent side = 2 m, and Hypotenuse = Length of the ladder (L).
Substitute the values:
cos60° = 2 / L.
From trigonometric values, cos60° = 1/2:
1/2 = 2 / L.
Solve for L:
L = 2 × 2 = 4.

If the altitude of the sum is at 60°, then the height of the vertical tower that will cast a shadow of length 30m is
We are given: - The angle of elevation of the sun (θ) = 60°, - Length of the shadow = 30 m. Using the tangent function: tanθ = (Height of the tower) / (Length of the shadow). Substitute the values: tan60° = Height / 30. From trigonometric values, tan60° = √3: √3 = Height / 30. Solve for Height: HeigRead more
We are given:

Substitute the values:
tan60° = Height / 30.
From trigonometric values, tan60° = √3:
√3 = Height / 30.
Solve for Height:
Height = 30 × √3 = 30√3 m.

Explain the significance of proper waste management in cooking activities and how it supports environmental sustainability.
Proper waste management during cooking is vital for maintaining cleanliness and reducing environmental impact. Segregating waste into wet (organic) and dry (non-organic) categories helps in efficient disposal. Organic waste like fruit peels and vegetable scraps can be composted, turning it into nutrRead more
Proper waste management during cooking is vital for maintaining cleanliness and reducing environmental impact. Segregating waste into wet (organic) and dry (non-organic) categories helps in efficient disposal. Organic waste like fruit peels and vegetable scraps can be composted, turning it into nutrient-rich soil for gardening. Recycling materials like plastic containers and paper reduces landfill waste. Responsible waste management promotes sustainability by conserving resources, reducing pollution, and encouraging eco-friendly practices in everyday cooking activities.

Managing food waste responsibly reduces environmental impact. Wet waste, like vegetable peels, can be composted to create natural fertilizers. Leftover food can be stored properly for later use or shared with those in need. Dry waste, including plastic packaging and wrappers, should be recycled. Proper segregation of waste in separate bins helps in efficient disposal. By following these practices, we contribute to a cleaner environment and support sustainable living.
