Answer:
17.4
Step-by-step explanation:
side 1=4.5
side 2=4.5
side 3=4.5
base 1=3.9
17.4
Step-by-step explanation:

We start with Left hand side
We know that csc(x) = 1/ sin(x)
So csc(2x) is replaced by 1/sin(2x)

Also we use identity
sin(2x) = 2 sin(x) cos(x)

4 divide by 2 is 2
Now we multiply top and bottom by sin(x) because we need tan(x) in our answer



We know that sinx/ cosx = tan(x)
Also 1/ sin(x)= csc(x)
so it becomes 2csc^2(x) tan(x) , Right hand side
Hence verified
Your answer is three out of the people in your school.
30%*470=141 (So the number of students in 8 grade is 141)
