Answer:sin75=√(2+√3)/2
Step-by-step explanation:
Cosx=1-2sin^2(x/2) let x=150
Cos150=1-2sin^2(150/2) cos150=-√3/2
-(√3)/2=1-2sin^2(75)
2sin^2(75)=1+(√3)/2
2sin^2(75)=(2+√3)/2
Cross multiply
2x2sin^2(75)=2+√3
4sin^2(75)=2+√3
sin^2(75)=(2+√3)/4
Take square root of both sides
sin75=√(2+√3)/√4
sin75=√(2+√3)/2
Joanna can assemble her bracelet in 30 ways.
<h3>How to find the number of ways in which the bracelet can be assembled?</h3>
It is given that Joanna has 6 beads and of those 6 beads, 2 are of the same color.
The rest 4 are of different colors.
Six beads can be arranged in a circle in 6!/6 ways.
This means that the six beads can be arranged in 5! ways.
Since this is a bracelet, it can be flipped around. Therefore, it can be arranged in 5!/2 ways.
5!/2 = 5*4*3*2*1/2
= 60
Now, we know that two beads are of the same color. Therefore, we must divide this by two again.
Therefore, we get:
60/2 = 30
The six beads can be arranged in 30 ways to make the bracelet.
Therefore, we have found that Joanna can assemble her bracelet in 30 ways.
