Final answer:
The length of the shadow of a building is 29m. We can use the Pythagorean theorem to find the height of the building.
Step-by-step explanation:
The length of the shadow of a building is 29m. We can use the Pythagorean theorem to find the height of the building. Let's assume the height of the building is 'h'.
Using the Pythagorean theorem, we have the equation h² + 29² = c², where c is the hypotenuse which represents the height of the building.
Simplifying the equation, we get h² + 841 = c². Now solving for c, we have c = √h² + 841. Since we have the value of c as 49m, we can substitute it in the equation and solve for h.
