Choose the abbreviation of the postulate or theorem that supports the conclusion that WAS NOT. Given: WS = NT, AS = OT, S = T.

koban [17]

Answer: The abbreviation that supports the conclusion is SAS

Step-by-step explanation:

Given WS=NT

AS=OT

S=T

We have two triangles named WAS and NOT

where we have two sides (WS=NT and AS=OT)

and an angle(S=T) equal

Since the angle is between the two sides

So the postulate that supports is SAS

i.e Side Angle Side

Find the vertex of the parabola y = 8x2.

murzikaleks [220]

Answer:

vertex is at (0,0)

Step-by-step explanation:

Find the vertex of the parabola y = 8x2.

I assume you meant y = 8* x^2

this can be compared to the general vertex form y = a (x - h)^2 + k

where vertex at (h, k)

so then...

h =0 and k = 0 here

vertex is at (0,0)

The angle of depression from the top of a cruise ship to the top of a sailboat is 22. Sitting above water, the cruise ship is 23

dusya [7]

Answer:

The distance between the cruise ship and the sail boat is 517 feet.

Step-by-step explanation:

The cruise ship is 236 feet tall, and the sailboat is 236 tall; this means the distance between the top of the cruise ship and the top of the sail boat is

236 feet - 27 feet = 209 feet.

We also know that the angel of depression from the top of the cruise ship to the bottom of the cruise ship is 22°. This forms a right triangle as shown in the figure attached.

Now from trigonometry we get:

$tan \: \theta = \dfrac{209}{d}$

$d= \dfrac{209}{tan\:\theta }$

$\boxed{d=517ft}$

The distance between the cruise ship and the sailboat is 517 feet.
