Answer:

Input work is the work done on a machine as the input force acts through the input distance. This is in contrast to output work which is a force that is applied by the body or system to something else. Output work is the work done by a machine as the output force acts through the output distance.Jan 15, 2020

Answer:

As per the properties of parallel lines and interior alternate angles postulate, we can prove that:

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

Step-by-step explanation:

<u>Given:</u>

Line y || z

i.e. y is parallel to z.

<u>To Prove:</u>

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

<u>Solution:</u>

It is given that the lines y and z are parallel to each other.

$m\angle 5, m\angle 1$ are <em>interior alternate angles </em>because lines y and z are parallel and one line AC cuts them.

So, $m\angle 5= m\angle 1$ ..... (1)

Similarly,

$m\angle 6, m\angle 3$ are <em>interior alternate angles </em>because lines y and z are parallel and one line AB cuts them.

So, $m\angle 6= m\angle 3$ ...... (2)

Now, we know that the line y is a straight line and A is one point on it.

Sum of all the angles on one side of a line on a point is always equal to $180^\circ$ .

i.e.

$m\angle 1+m\angle 2+m\angle 3=180^\circ$

Using equations (1) and (2):

We can see that:

$m\angle 5+m\angle 2+m\angle 6=180^\circ$

<em>Hence proved.</em>

HELP PLZZZ!!!! What is the approximate area of a circular pond?

Georgia [21]

Answer:

<h2>B. 49,062.5 ft²</h2>

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

We have the diameter d = 250 ft. We know: d = 2r.

Therefore r = 250 : 2 = 125 ft.

Substitute:

$A=\pi(125)^2=15625\pi$

$\pi\approx3.14\to A=(15625)(3.14)=49062.5\ ft^2$
