Answer: 
Step-by-step explanation:
We can list the possible rational roots of this polynomial using the Rational Root Theorem. This theorem states that all the possible rational roots of an equation follow the structure
, where <u>p is any of the factors of the constant term and q is any of the factors of the leading coefficient</u>.
In this example, -15 is the constant term and 1 is the leading coefficient (
has a coefficient of 1).
The factors of -15 are
, while the factors of 1 are
. <em>p </em>is can be any one of the factors of -15, while <em>q</em> can be any of the factors of 1.

The possible roots can be any of the numbers on the top divided by any of the numbers on the bottom. Since dividing by 1 or -1 won't change any of the numbers on the top, the rational roots of this function are
.
Answer:
acute angle is less than 90, so we have 4 acute angles between the inner lines. Also we have 3 more acute angles combining the above angles. So the total will be 7 acute angles.Nov 9, 2016
