X= 24 because both side lengths are the same size. So it would be 24. hope it helped.
So this in the exponential form of ab^x, where a is the y intercept, b is the growth factor(base) and x is your domain. From this, we can answer each question. The initial amount is 800, growth rate is 32% and factor is 1.32.
Happy learning!
No because the number has to be between 1 and 10 so it should be 2.6x10^3
If this is supposed to be

Then this can simply be reduced to

by the double angle formula for cosine
