 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)

Which set(s) of points show x in DIRECT PROPORTION to y?
vredina [299]

Answer: OPTION D.

Step-by-step explanation:

For this exercise it is important to remember that:

1.  Direct proportion equations have the following form:

y=kx

Where "k" is the constant of proportionality.

2. The graph of Direct proportions is an straight line that passes through the origin.

Observe the picture attached.

If you join the points G, C and A, you get a straight line that passes through the origin,

If you join the points F, G and H, you also get a straight line that passes through the origin,

Therefore, the sets of points show "x" in Direct proportion to "y", are:

\{F, G, H\} and   \{{G, C, A}\}
