The angle of elevation of the top of a tower from a point A due north of it is a and from a point B at a distance of 9 units due west of A is cos-1313. If the distance of the point B from the tower is 15 units, then cot α is equal to: 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
