Respuesta :

Answer: AB= 24 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle we have to apply the Pythagorean Theorem:  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case CB ) and a and b are the other sides.  

Replacing with the values given:  

CB^2 = CA^2 + AB^2  

25^2 = 7^2 + x^2  

Where x is the value that we are searching for..

625= 49 + x^2

625 -49 = x^2

576 = x^2

√576 = x

24 = x

So, AB= 24 ft
