Which of the following is rational? 1) 3xPi

2) 2/3+9.26

3) \/45+\/26

4) 14.3+5.7876239...

BTW this ( \/ ) means the squared sybol. i did it like that because iididn't know how to do the squared symobl on a keyboard.

And the 3 in 14.3 is a repeating 3

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
