Solved Example Clockple on Angle of ElevationQues: The angle of elevation of the top of a pole measures 48� from a point on the ground 18 ft away from its base. Find the height of the flagpole.Solution:

Step 1: Let�s first visualize the situation. 

Step 2: Let �x� be the height of the flagpole.

Step 4: � x = 18 � tan 48� = 18 � 1.11061� = 19.99102��

20

Step 5: So, the flagpole is about 20 ft high.

Solution ko:

Tan48=x/18

X=(tan48)(18)

X=(1.1106)(18)

X= 19.99 or 20ft.
