Questions & Step-by-Step Solutions
If a kite is flying at a height of 100 meters and the angle of elevation from a point on the ground is 60 degrees, how far is the point from the base of the kite?
Correct Answer: 50 meters
Step 1: Understand that the height of the kite is 100 meters.
Step 2: Know that the angle of elevation from the ground to the kite is 60 degrees.
Step 3: Visualize a right triangle where the height of the kite is one side (100 meters) and the distance from the point on the ground to the base of the kite is the other side.
Step 4: Use the tangent function, which relates the angle of elevation to the opposite side (height) and the adjacent side (distance). The formula is: tan(angle) = opposite / adjacent.
Step 5: For our problem, we have tan(60 degrees) = height / distance.
Step 6: Rearrange the formula to find the distance: distance = height / tan(60 degrees).
Step 7: Substitute the height (100 meters) into the formula: distance = 100 / tan(60 degrees).
Step 8: Calculate tan(60 degrees), which is √3 (approximately 1.732).
