Did you mean 360 divided by 20?
9514 1404 393
Answer:
p = 30
angles 30°, 45°; exterior: 75°
Step-by-step explanation:
The exterior angle is equal to the sum of the remote interior angle:
3p -15 = p + (p +15)
p = 30 . . . . . . . . . . . . . add 15-2p
The interior angles are 30°, 45°; the exterior angle is 75°.
ANSWER
The correct answer is

EXPLANATION
The number

is a rational number.
Since the set of rational numbers is closed under addition, the number that should be added to

should also be a rational number in order to get another rational number.
This means that, if we add a rational number to an irrational number we get an irrational number.
The only rational number in the options provided is

We add it to

to get

Note that,

Hence the result is a rational number.
As for the remaining options,

are irrational numbers, so adding them to

will not produce a rational number.
Answer:
