As john walks 50 ft towards a chimney, the angle of elevation from his eye to the top of the chimney changes from 30° to 45°. identify the height of the chimney rounded to the nearest foot. 80 ft 50 ft 68 ft 96 ft

Observe the image attached. In this triangle ABD, AD is the height of the chimney. Let BC be the distance traveled by John towards the chimney. As we can observe in the image how the angle of elevation changes from to .

In the triangle ABD,

Let the distance CD be x meters.

(Equation 1)

In the triangle ACD,

(Equation 2)

Substituting the value of x from equation 2 in the equation 1,

h= 68.3 feet.

step-by-step explanation:

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
