Approximately 61.
if you divide 420 by 6.82 you get 61.58 :)
For this case what you should know is that the slope of the line can be calculated as:
Tan x = sin x / cos x
The lines x = 2 and x = 3 have an angle of 90 degrees with respect to the x axis:
Tan 90 = sin 90 / cos 90 = 1/0 = inf
Therefore, both lines have a rate of change that tends to infinity.
answer
Both lines have the same slope (infinity) Both are greater than m = -1
8x = 54 - 6.
Then lets solve the equation. :)
8x = 48.
x = 6.
Hope it helps! :)
