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.
Answer:
49
Step-by-step explanation:
Let be the unknown number. Twice means times 2. So, the mathematical sentence should be .
Divide both sides by 2.
To remove the radical symbol, raise both sides to the second power.
Thus, the answer is 49. Twice the square root of 49 is equal to 14.
