csc(2x) = csc(x)/(2cos(x))
1/(sin(2x)) = csc(x)/(2cos(x))
1/(2*sin(x)*cos(x)) = csc(x)/(2cos(x))
(1/sin(x))*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)/(2*cos(x)) = csc(x)/(2cos(x))
The identity is confirmed. Notice how I only altered the left hand side (LHS) keeping the right hand side (RHS) the same each time.
It is 16.50 because 9 divided by 6 is 1.5. so 1.5 is the unit rate. 1.5 x 11 = 16.5
Because this is an isosceles triangle, 3x = x + 10. Thus, 2x + 10 and x = 5.
With x=5, MN has the length 5+10, or 15.
Answer:
i think it's 2.2
Step-by-step explanation:
it looks like (5,11) is a point that the line crosses so when you divide 11 by 5, would get 2.2
