<u>4 sec²(x) = 8</u>
Divide each side by 4: sec²(x) = 2
Take the square root of each side: sec(x) = + or - √2
We know that sec(x) = 1/cos(x)
So the equation becomes 1/cos(x) = + or - √2
Divide '1' by each side: cos(x) = + or - (1/2) √2
x = <em>45°, 135°, 225°, 315°
</em>

Answer:
the answer is 37.68
Step-by-step explanation:
C=2 x pi x r
C = 2 x 3.14 x 6 the radius is 6 because you divide the diameter by 2 to get the radius which is 6 in thsi case.
