For problems 1-5, use the unit circle to calculate the given values. 1. cos 120
2. sin 30
3. tan 150
4. sin 240
5. cos 300

step-by-step explanation:

mean or average is 40.6

i think the length is 12 and the width is 17

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
