Which of the following lists the angles from smallest to largest?

a) R, S, T

b) S, T, R

c) T, R, S

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

Which one is the correct answer, and why?
