<PRE><B>Question 524729</B>
Approximate to the nearest degree, the solutions of the equation in the interval [0°, 360°). 
(8cot(x)+1)(cos(x)-4)=0
---
8cot(x) = -1 or cos(x) = 4
---
cos(x) cannot = 4, so cot(x) = -1/8
x = cot^-1(-1/8) = -82.88  = 277.125 degrees
or x = 277.12-180 = 97.125 degrees
