How many diagonals can be constructed from one vertex of an n-gon? State your answer in terms of n and, of course, justify your
Rasek [7]

Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).

Alexeev081 [22]

Answer:

BC = 23.8

Step-by-step explanation:

See the diagram attached.

Given AC ║ DE and BD = 5, DA = 12 and BE = 7.

We have to find BC.

Since, AC ║ DE, so, Δ ABC and Δ DBE are similar.

If two triangles are similar then the ratio of their corresponding sides remains the same.

Hence, \frac{BD}{BA} = \frac{BE}{BC}

⇒ \frac{5}{12 + 5} = \frac{7}{BC}

⇒ BC = \frac{7 \times 17}{5} = 23.8 (Answer)

Can someone please help me with this ?
Reil [10]

Answer:

y intercept=15 and slope is 3

Step-by-step explanation:

Ok so for this one we know the y intercept is 15 because the y intercept is wherever x=0 and in the table when x=0 y=15

to find slope we use (y2-y1)/(x2-x1) which when we put points (0,15) and (1,18) in for would be:

(18-15)/(1-0)

3/1

= 3
