Answer:
c
Step-by-step explanation:
now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.
namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°. Thus cos(1140°) = cos(60°).
what's that cosine of 60°? Check the picture below.
The the first one and the third one
Answer:
x=5
Step-by-step explanation:
1) Group like terms which will then make the equation 4x-2(x-5)=5x-5
2) Expand the equation (multiply) which will make it 4x-2x+10=5x-5
3) Add similar elements; 2x+10=5x-5
4) Subtract 10 from both sides; 2x=5x-15
5) Subtract 5x from both sides; -3x=-15
6) Divide by 3; x=5
