The rational number among all the answer choices is; Pi + √16.
<h3>What is a Rational number?</h3>
A rational number by definition, is one that can be represented as the quotient a/b of two integers in which case b ≠ 0.
On this note, it follows that since the constant pi is; 22/7, the number pi + √16 can be represented as a rational number as follows;
22/7 + 4 = 50/7.

Answer:
all choices apply
Step-by-step explanation:
Angles are "adjacent" when they share a vertex and the ray between them. Thus the following pairs are adjacent:
- 90° and ∠A
- ∠A and ∠B
- ∠B and ∠C
- ∠C and 27°
- 27° and 90°
A linear pair is an adjacent pair in which the non-common rays point in opposite directions (lie on the same line). The angles of a linear pair total 180°, so are supplementary.
These pairs of angles are supplementary:
Vertical angles are not adjacent, but share a vertex and have sides that are opposite rays. They are supplementary to the same angle. here, angles A and C are a vertical pair.
All of the answer choices apply.
