Part A: y= 1/3x + 1
Part B: y=3x +4
Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Here ya go.
-n - 6n + 4 = 53
(Combine like terms)
-7n + 4 = 53
-7n = 53 - 4
-7n = 49
n = -7
14 = 6n + 6 - 2n
(Combine like terms)
14 = 14n + 6
-4n = 6 - 14
-4n = -8
n = 2
It would be 92 units because if you multiply the nonagon below
