12a. First expressing as a fraction, Shan has 12/32 books from his favorite author, so:
12/32=3/8=0.375 books from his favorite author
12b. Because the decimal 0.375 isn't a periodical decimal, so it would be a terminating decimal.
•sum of the angles in a triangle = 180°
•sum of the angle in a quadrilateral = 360°
•opposite angles are equal
•for two parallel lines and a transversal, corresponding angles are equal, and alternate angles are equal.
•If it already has an angle for a triangle subtract that by 180 and divide it by two you have the other two angle, if you already have two angles on a triangle add those together and subtract from 180 thats the last angle, same for a quadrilateral but you subtract by 360 instead.
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Divide both sides by 20:</u>
<u>Simplify:</u>
The answer is 403, just try simple long division.
I think its d, because A and Cs angles make 180. And B has two equal sides that make it possible to make a triangle. Sorry i couldnt be more helpful
