Step-by-step explanation:
Using the concept of pythagoras theorem, here we have the base and hypotenuse given hence we need to find the third dimension, assuming the wall is perfectly straight and forms a right angle with the bsse of the ladder. Here,
and making a the subject of the formula then
and substituting 30 ft for c and 0.25*30=7.5 ft for b then
