a 32m tall building cast a shadow. the distance from the top of the building to the tip of the shadow is 35m. find the length of
icang [17]

The length of the shadow is 14.2 m

Right angle triangle:

Right angle triangle has one of its sides as 90 degrees.

The height of the building is the opposite side of the triangle.

The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.

The length of the shadow is the adjacent side of the triangle.

Therefore,

c² = a² + b²

b² = 35² - 32²

b² = 1225 - 1024

b² = 201

b = √201

b = 14.17

b = 14.2 m

Hence the length of the shadow is 14.2 m.
