Answer:
a) a = 60° b = 60° c = 120° d = 60°
b) a = 140° b = 20° c = 60° d = 60°
Step-by-step explanation:
a) Sum of the angles of a hexagon = (6 - 2)180 = 720
Since the hexagon is regular, c = 720/6 = 120
a and c are supplementary, so a = 180 - 120 = 60
d = 120/2 = 60
b)
sum of the angles of a nonagon = (9 - 2)180 = 1260
a = 1260/9 = 140
140 + 2b = 180
2b = 40
b = 20
c = 60 and d = 60 (This is really difficult to explain with the vertices being labeled)
The answer is 270 degrees.
Since a circle has a full degree measure of 360 degrees, we can multiply 360 by 3/4 to result in 270 degrees.
Hope this helps.

Answer: y = 40x + 750
Step-by-step explanation:
Linear model;
y = mx + c
y is the total cost of buying granite counter tops for a certain number of square foot as well as the cost to install the counter top.
m is the cost of granite counter tops per square foot which is $40 in this case.
x is the number of square feet required.
c is the base pay for the installation of the counter top which is $750
Linear model will therefore look like this;
y = 40x + 750
To test it. Assume you want enough granite tops for 10 square feet. How much would it cost;
= 40 (10) + 750
= $1,150
Answer:
(a, 0)
Step-by-step explanation:
Point S has the same x-coordinate as does Point R: a.
Point S has the y-coordinate 0, as Point S lies on the x-axis.
Correct final answer: (a, 0) represents Point S.
