Question should be sin 20 cos 10 + cos 20 sin 10
remember sin (a+b) = sin a cos b + cos a sin b ?
sin 20 cos 10 + cos 20 sin 10
= sin (20+10)
= sin 30
= 1/2
The way to determine the number of solutions is to complete the problem in multiple different ways.
Answer:
12
Step-by-step explanation:
1. No idea
2. Angle A
3. Line RT
4. NO, 4/2 = 2, 5/3 = Not 2
5.Asking someone else?
6. 6 ft.
7. 10.56, precisely
8. 90 degrees
9. 51 degrees
10. 24 ft.
That would be 1953.08
diameter = <span>circumference/pi, so reverse it and multiply 622 by 3.14</span>
