Answer:
45% round 55% rectangular
7cos(x) + 1 = 6sec(x)
7cos(x) + 1 = 6/cos(x)
7cos^(x) + cos(x) = 6
7cos^(x) + cos(x) - 6 = 0
[7cos(x) - 6][cos(x) + 1] = 0
cos(x) = 6/7 , x = arccos(6/7) and
cos(x) = -1, x = 180
6 times 10^4 is your answer hope i helped
C is the correct answer because in a title, you always want to capitalize the bigger and more describing words.
Hope this helped!
