- A mathematical journey of trigonometry.Few daily life applications of trigonometry.
- 100ft
- We know that opposite/hypotenuse is sinθ,which is 100/200 and that will be 0.5. So the angle angle from the ground to the top of the house will be 30°.
- ?
- 200ft
- Let's find out the angle from the ground to the top of the house.
- We know that perpendicular/base is tanθ, which is 15/15=1. So the angle from the river bank will be 45°.
- 15ft
- 15ft
- Let us find the angle form the other river bank to the top of the tree.
- ?
- We know that sin=perpendicular/hypotenuse, which is 1/2=20/hypotenuse(30°=1/2) . So the length of the door is 10cm.
- ?
- 20cm
- 30°
- Let us now find the lenght of the door.The angle from the water cooler to the door is 30° and the distance from the water cooler to the top the door is 20cm.
- We know that sinθ=perpendicular/hypotenuse which is sin60°=3/hypotenuse that is √3/2 = 3/hypotenuse. so the distance from the ground to the top of the school is 2√3m.
- 60°
- ?
- 3m
- Let us now find out the length from the ground to the top of the school.
- THE END
