cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
Answer:
19 dollars
Step-by-step explanation:
To find out how much the cost was for each person, you take the total cost and divide by the number of people...
589/31
=19
270 divided by 3 = 90.
90 is the cost per person.
Now you do 90 times 10 to get the total for all 10 people.
90 times 10= 900.
83620 the 2 is in the 10s place and on 208 the 2 is in the 100s place so the 2 in 208 is 10 times bigger than the 2 in 83620 I hope i'm right sorry if your not
