Questions & Step-by-Step Solutions
A kite is flying at a height of 30 meters. If the angle of elevation from a point on the ground to the kite is 60 degrees, how far is the point from the base of the kite's height?
Correct Answer: 10√3 meters
Step 1: Understand that the height of the kite is 30 meters.
Step 2: Know that the angle of elevation from the ground to the kite is 60 degrees.
Step 3: Recall the relationship between height, distance, and angle in a right triangle: height = distance * tan(angle).
Step 4: Rearrange the formula to find distance: distance = height / tan(angle).
Step 5: Substitute the height (30 meters) and the angle (60 degrees) into the formula.
Step 6: Calculate tan(60 degrees), which is √3.
Step 7: Substitute tan(60 degrees) into the formula: distance = 30 / (√3).
Step 8: To simplify, multiply the numerator and denominator by √3: distance = 30√3 / 3.
Step 9: Simplify the fraction: distance = 10√3 meters.
Trigonometry – The problem involves using the tangent function to relate the height of the kite and the angle of elevation to find the horizontal distance.
Right Triangle Properties – Understanding the relationship between the sides of a right triangle formed by the height of the kite and the distance from the point on the ground.
