Answer:

Area= 50√3 units^2

Step-by-step explanation:

Given:

In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.

As the given triangle is SAS triangle, we'll use the following formula to calculate its area:

A=1/2absinC

where a= 20

b= 10√3

and c=30°

Now putting values we get:

A=(1/2)(20)(10√3) sin(30)

=100√3(1/2)

=50√3

so the area is 50√3 units^2 !

20k + 50
so remember factorise means to add brackets in.this will be a single bracket so we need a number / letter that will go outside the bracket.in this case it will be a number because 50 dosent have a letter only 20 has a letter which is k. you need to put the highest number that goes into both numbers on the outside of the bracket which is 10.
20k + 50
=10(2k + 5)
to check if it's right we simplify it out using a fraud method or whoever method your comfortable with.
10(2k+5)
10*2k=20k
10*5=50
=20+50k
so it is factorised correctly.
answer is 10(2k+5)

GEOMETRY!!! Will give brainliest

I think it’s square because there is a cross section on the two sides of the square that are parallel to each other :)

What are the coordinates of the midpoint of the line segment with endpoints 2,5 and 4,-7

Phoenix [80]

<h3>Answer: (3, -1)</h3>

===============================================

Explanation:

The midpoint formula is $(x_m, y_m) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$

This basically says to add the corresponding coordinates and divide by 2.

The given points (2,5) and (4,-7) have x coordinates of 2 and 4. They add to 2+4 = 6, and then that result cuts in half to 6/2 = 3. The x coordinate of the midpoint is 3.

The y coordinate of the midpoint is y = -1 since adding the y coordinates of the given points leads to 5+(-7) = -2 which cuts in half to -1.

So overall the midpoint is located at (3, -1)

The point C(2,3) is translated along a vector that is parallel to the line y=3x-2. The translation vector has magnitude square r

qaws [65]

Step-by-step explanation:

The translation vector v can be resolved into its x and y components, where x² + y² = 10 (Pythagoras' Theorem) and y = 3x

(parallel to y = 3x - 2, slope = 3).

We have x² + (3x)² = 10,

=> x² + 9x² = 10, 10x² = 10, x = 1 or x = -1.

When x = 1, y = 3. When x = -1, y = -3.

Therefore 2 possible translation vectors

are (1, 3) or (-1, -3).

First new C' = (2 + (1), 3 + (3)) = (3, 6).

Second new C'= (2 + (-1), 3 + (-3)) = (1, 0).

The possible images are (3, 6) and (1, 0).

A dolphin is at -- 28 feet. It swims up and jumps out of the water to a height of 8 feet. Find the vertical distance the dolphin

Helga [31]

Answer:

The vertical depth travelled by the dolphin = 36 feet

Step-by-step explanation:

The dolphin is a fish that can jump out of the water and therefore it is used in circus shows and exhibitions.

Initially the dolphin is at a depth of 28 feet deep inside the water surface.It comes to water surface and then jumps out of the water to a height of 8 feet.

The vertical distance travelled by the dolphin can be found by taking the difference of final height and initial depth.

Vertical depth = final height - initial depth

= 8 - (-28)

= 36 feet

The vertical depth travelled by the dolphin = 36 feet
