Answer:
x = 0 , π
Step-by-step explanation:
- Rewrite it by using the identity
- Add 4sin x to both the sides.
- Take sin x common from the expression in L.H.S.
Here , we can get two more equations to find x.
1) 
- Divide both the sides by sin x
- Substract 4 from both the sides.
2)
- Divide both the sides by (sin x + 4)
over interval [0 , 2π).
Step-by-step explanation:
1.77 would be closer to 2
<span>For example
let there be 100 students
so the number of girls=40
20% of girls=20%of40=20*40/100=8 wear glasses
Which means 8 out of 100 students wear glasses
So 8%students wear glasses</span>
Answer:
1 and 2 are vertical angles; 5 and 6 are adjacent angles.
Step-by-step explanation:
Vertical angles are opposite angles that share only a vertex. This describes angles 1 and 2.
Adjacent angles are angles that share a common side and a common vertex. This describes angles 5 and 6.
