Answer:

Step-by-step explanation:

Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.

This is because two angles are zero and top is a straight line, and a line is 180 degrees!

hopes this helps :)

A cargo plane flew from the US across the Atlantic at 212 mph, and flew back to the US at 232 mph. Given that the first trip too

expeople1 [14]

The return trip was 21.2 hours long.

Step-by-step explanation:

Given,

Speed of plane from US = 212 mph

Speed of plane on return trip = 232 mph

Let,

x be the time taken on return trip.

Time taken from US = x+2

We know that;

Distance = Speed * Time

Distance of plane from US = 212(x+2) = 212x+424

Distance on return trip = 232x

As the distance will be same, therefore,

$232x=212x+424\\232x-212x=424\\20x=424$

Dividing both sides by 20

$\frac{20x}{20}=\frac{424}{20}\\x=12.2\ hours$

The return trip was 21.2 hours long.

Find the distance between the two points～<br>A ( 7 , 4 ) and B ( 3 , 2 )<br><br><br>thankyou!

Answer:

AB = $\sqrt{20}$

Step-by-step explanation:

calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = B (3, 2 ) and (x₂, y₂ ) = A (7, 4 )

AB = $\sqrt{(7-3)^2+(4-2)^2}$

= $\sqrt{4^2+2^2}$

= $\sqrt{16+4}$

= $\sqrt{20}$

≈ 4.47 ( to 2 dec. places )
