A ladder leaning against a 20ft wall, with an angle of 32 degrees with respect to the wall, must be 24ft long.
cos(theta) = adjacent over hypotenuse
cos(32) = 20 / hypotenuse
hypotenuse = 20 / cos(32)
hypotenuse = 23.58
Then an angle of 58 degrees will be at the bottom of the ladder. Use trigonometry and the sine ratio: sin = opp/hyp and hyp = opp/sin hyp = 20/sin(58) = 23.58356807 length of ladder = 24 feet to the nearest foot
23.58 feetA+no its not i just tryed it so yea get your facts right before putting them on herebut i dont even know this so srry for the ppl look for it
The ladder forms the hypotenuse (r) and the wall forms the vertical (y) of a right triangle. sin theta = y / r the angle at the bottom is (90 - 32) = 58 sin 58 = 20 / r r = 20 / sin 58 = 23.583568067241928552025478405751 feet ladder must be about (rounding) 23.6 feet long.
A ladder should be place at 1m form the base of the scaffold .
It would be a 0 degree angle or a 180 degree angle depending upon if they are aimed the same direction or opposite.

It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.
No. They form an angle.
It would be a 0 degree angle or a 180 degree angle depending upon if they are aimed the same direction or opposite.
Yes
When two lines intersect to form a 90o angle, they are said to be perpendicular.
