Answer: AB= 24 ft
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
