Answer:
C. 168°
Step-by-step explanation:
The exterior angle at any vertex of an n-gon will be ...
360°/n
So a 30-gon will have exterior angles of ...
360°/30 = 12°
The adjacent interior angle is supplementary to this, so is ...
180° -12° = 168°
_____
<em>Using the reasonableness test</em>
You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.
Answer:
The answer is -2
Step-by-step explanation:
It goes down 2 and the line is to the left, meaning its negative :)
195min/1.5 miles so 130 min / 1 mile or 2h 10min (2 1/6h)
Answer:
The answer for this is 7.059
Step-by-step explanation:
PV = nRT.......divide both sides by nR
(PV) / (nR) = T
