The measure of the interior angle of a regular polygon is 180(n-2)/n for n sides.
14.
135 = 180(n-2)/n.
135n = 180n-360
45n=360
n= 8, 8 sides
15. 166.5n=180n-360
n= 26 sides
16. Since the shape is marked as a parallelogram, the angle at D is 180-angle at A= 180-115=65 degrees.

identify a two-digit dividend that will result in a quotient with a remainder 1 when the divisor is 4
Afina-wow [57]
17, 21, 25, etc. because when you divided 4 by any of these numbers you will get your answer with a remainder of 1. For example, 17/4 is 4 R.1 because 4 times 4 is 16, then you will have one left over. (At my school you always go to a decimal not a remainder)

Solve for x: 4 over 5 x + 4 over 3 = 2x x = __________________ Write your answer as a fraction in simplest form. Use the "/" sym
Vesna [10]
4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.

with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x

without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x
