What is the measure of each interior angle of a regular 10 sided polygon?

If f(x) = 2x + 2 and g(x) = x? , what is (gºf)(2)?

Yo need asap pls ! markin da brainiest too !

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
