100 POINTS! PLEASE HELP!
Semmy [17]

Apply angle bisector theorem

\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}

\\ \sf\longmapsto 9x=5(2x-1)

\\ \sf\longmapsto 9x=10x-5

\\ \sf\longmapsto 10x-9x=5

\\ \sf\longmapsto x=5

#2

\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}

\\ \sf\longmapsto 4(2.25)=3x

\\ \sf\longmapsto 3x=9

\\ \sf\longmapsto x=3

Hope it helps

Using diagonals from a common vertex, how many triangles could be formed from the polygon pictured below?
Ad libitum [116K]

9514 1404 393

Answer:

  3

Step-by-step explanation:

From a given vertex, two of the vertices are adjacent, so a "diagonal" to those will not form a triangle. The number of diagonals that can be drawn is 3 fewer than the number of sides. The number of triangles is 1 more than the number of diagonals.

For a 5-sided figure, 2 diagonals can be drawn from a common vertex.

  3 triangles will be formed.

What's the length of AB?​
Nastasia [14]
Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.

Please help me I don’t know
Verizon [17]

Answer: A


Step-by-step explanation: Domain is the input, or x values. You can see the points (1, 6), (2,3), (3,1), and (6,5). In ordered pairs, the x values are the numbers on the left:

(x, y)

So if we take all the numbers on the left, we get 1, 2, 3, and 6. Thus, our domain is {1,2,3,6}
