The length of a shadow of a building is 28m . The distance from the top of the building to the tip of the shadow is 38m. Find the height of the building

The height of the building is 2√165 (m)

Step-by-step explanation:

You can imagine that the distance from the top of the building to the tip of the shadow is like hypotenuse, the length of a shadow of a building is like squared angle edge

Assume the height of the building is x

According to  Pythagorean theorem:

28^2 + x^2 = 38^2

x^2 = 38^2 - 28^2

x = √(38^2 - 28^2)

x= 2√165 (m)

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

6 and 24

step-by-step explanation:

6 x 4 = 24
