Answer: I think 91.9
Step-by-step explanation:
If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9

Answer:
15/30= 1/2 of 50%
Step-by-step explanation:
" the product " means multiply
(2ab + b)(a^2 - b^2) = 2a^3b - 2ab^3 + a^2b - b^3
when multiplied : (2a + b)(2a^3b - 2ab^3 + a^2b - b^3) =
4a^4b - 4a^2b^3 + 2a^3b - 2ab^3 + 2a^3b^2 - 2ab^4 + a^2b^2 - b^4
...result is a polynomial with 8 terms
