1 / cos^2 O - 3 / cos O - 2 = 0
1 - 3 cos O - 2 cos^2 O = 0
2 cos^2 O + 3 cos O - 1 = 0
cos O = 0.2807 , -1.78 ( -1.78 cannot be a solution)
O = 74 degrees (from 0.2807) another solution is 360-74 = 286 degrees
Its D
Answer:
Hey there!
A line perpendicular to y=3x+5 would have a slope of -1/3.
Thus, the problem now becomes to write a line in point slope form with a slope of -1/3, and that passes through (4, -1)
y+1=-1/3(x-4), would be your answer.
Hope this helps :)
B. would be 6.78 and C. would be .067. Hope this helped
Answer:
