A ladder is placed against a wall, such that it touches the top of the wall 6 meters above the ground. The ladder is inclined at an angle of 53 degrees. Find how far the ladder is from the foot of the wall.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
