Answer:
it is 23. always remember it's supposed to add up to 180. So add up all your numbers and subtract the total from 180 to get your answer
Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))". That is, you plug something in for x, then you plug that value into g, simplify, and then plug the result into f. hope this helps.
Absolutely not. The least mixed numbers are 1 and 1/2, and 1 1/2 + 1 1/2 is 3, so no, it is not possible. Hope I helped!
if your asking for the equation, it's t + 7 < 3
