Question

How can the cotangent of an angle in a right triangle be calculated?
Answer

by dividing the adjacent side by the hypotenuse

by dividing the adjacent side by the opposite side

by dividing the hypotenuse by the opposite side

by dividing the hypotenuse by the adjacent side

Answer 1

cotx = cosx/sinx
cosx is adjacent / hypot.
sinx is opposite / hypot.
therefore cotx = (adj/hyp) / (opp/hyp)
hypotenuses cancel and you get
adj/opp

Answer 2

cotangent of a right triangle is defined to be the ratio o adjacent side & opposite side

Answer 3

find tan of the angle the find the reciprocal
