Questions & Step-by-Step Solutions
A person is standing 25 meters away from a vertical pole. If the angle of elevation to the top of the pole is 36.87 degrees, what is the height of the pole?
Step 1: Understand the problem. You have a person standing 25 meters away from a pole and you need to find the height of the pole.
Step 2: Identify the angle of elevation. The angle of elevation to the top of the pole is given as 36.87 degrees.
Step 3: Use the tangent function. The tangent of an angle in a right triangle is the ratio of the opposite side (height of the pole) to the adjacent side (distance from the pole).
Step 4: Write the formula. The formula is tan(angle) = height / distance.
Step 5: Plug in the values. Here, angle = 36.87 degrees and distance = 25 meters. So, tan(36.87°) = height / 25.
Step 6: Find tan(36.87°). The value of tan(36.87°) is approximately 0.75.
Step 7: Rearrange the formula to find height. height = distance * tan(36.87°).
Trigonometry – The problem involves using the tangent function to relate the angle of elevation to the height of the pole and the distance from the pole.
Right Triangle Properties – Understanding the relationship between the sides of a right triangle formed by the pole, the ground, and the line of sight.
