Answer:

C. 360

E. 720

Step-by-step explanation:

note: 2pi radians = 360 degrees.

Cos(x) = 1  whenever x = 2k pi where k is an integer, thus

This translates to

cos(x) = 1 when x=0, 360, 720, 1080, ... degrees.

Between 270 and 810, the angles that satisfy cos(x) = 1 are

360 and 720.

So choose C and E

Solve. 3(4x + 2x) = 8
shepuryov [24]
If you would like to solve the equation 3 * (4 * x + 2 * x) = 8, you can do this using the following steps:

3 * (4 * x + 2 * x) = 8
3 * 6 * x = 8
18 * x = 8    /18
x = 8/18
x = 4/9

The correct result would be 4/9.
