Question

Can someone help me with this word problem please? It’s for the Pythagorean theorem

Answer 1

Step-by-step explanation:

Mark forms a right angle to the building as shown in the above diagram. The ladder lenght is the hypotenuse of this triangle, therefore we can use Pythagoras to calculate the length.

`\begin{gathered} Ladder\text{ = }√(12^2+5^2) \\ \text{ =13} \end{gathered}`

Answer: ladder length = 13
