Question: From a point on the ground, the angle of elevation to the top of a hill is 45 degrees. If the height of the hill is 50 m, how far is the point from the base of the hill?

Options:

25 m
50 m
70 m
100 m

Correct Answer: 50 m

Solution:

Using tan(45°) = height/distance, we have 1 = 50/distance. Therefore, distance = 50 m.

From a point on the ground, the angle of elevation to the top of a hill is 45 degrees. If the height of the hill is 50 m, how far is the point from the base of the hill?

Correct Answer: 50 m

Step 1: Understand that the angle of elevation is the angle formed between the horizontal ground and the line of sight to the top of the hill.
Step 2: Identify that the height of the hill is 50 meters.
Step 3: Recognize that the angle of elevation is 45 degrees.
Step 4: Use the tangent function, which relates the angle of elevation to the height and distance from the base of the hill. The formula is: tan(angle) = height/distance.
Step 5: Substitute the known values into the formula: tan(45°) = height/distance, which becomes tan(45°) = 50/distance.
Step 6: Know that tan(45°) equals 1. So, the equation simplifies to 1 = 50/distance.
Step 7: Rearrange the equation to find the distance: distance = 50/1.
Step 8: Calculate the distance, which equals 50 meters.
