algebra 1 I NEED HELP!!

the bottom of a 25-foot ladder is placed 7 feet from a wall. How far will the ladder reach up?

Since the ladder, wall, and ground form a right triangle, you can use this formula:

A squared + B squared = C squared

A = 7 feet
C = 25 feet
B = distance the ladder will reach

49 + B squared = 625
B squared = 625 - 49
B = square root of 576
B = 24 feet
