→ Substitute cos 2x and sin 2x by their expressions

→ Subtract both sides by sin x

→ Take sin x as a common factor in the right side

From the graph, the equation has 4 solutions, the intersection points between the 2 graphs
Answer:
4
Step-by-step explanation:
Answer:
1/7
Step-by-step explanation:
The left over fraction is divided among the three children as follows
Given
Left over as 3/7
Number of children 3
Quantity each gets will be 3/7÷3
3/7÷3=3/7*1/3=3/21
By simplyfying the fractions, 3/21 when both the numerator and denominator are divided by 3 we obtain that 3/21=1/7
Therefore, each child geta 1/7
13/21 cause 21 is a common denominator and 7x3+ 21 you have to do 7x=7 and 3x7=21 so you have to do 3x2= 6 so you do 6+7 which equals 13 and your answer is 13 over 21 since it can't be simplified
