An observer is standing 30 feet from a hlagpole. She is lookingat the top of the flagpole. How tall is the flagpole. Round tothe nearest tenth if necessary.

Flagpole is 21.7ft tall
Explanation:From the diagram given:
opposite = x
adjacent = 30 ft
hypotenuse = 37 ft
Using pythagoras' theorem:
Hypotenuse² = opposite² + adjacent²
37² = x² + 30²
1369 = x² + 900
1369 - 900 = x²
x² = 469
x = √469
x = 21.66 ft
To the nearest tenth, x is 21.7 ft
Flagpole is 21.7ft tall
