30 meter building casts a shadow the distance from the top of the building to the tip of the shadow is 37 M find the length of t

Pavlova-9 [17]

Answer: 22 meters

Step-by-step explanation:

Draw a picture of a right triangle and label the height as 30 meters and the hypotenuse as 37 meters. Use the Pythagorean Theorem to find the base (the length of the shadow).

a² + b² = c²

x² + 30² = 37²

x² = 37² - 30²

x² = 1369 - 900

x² = 469

√x² = √469

x = 21.656

x ≈ 22
