Find the distance between each pair of points. Round your answer to the nearest tenth. (-6, -5) and (2, 0)
Anna71 [15]

Answer:

The answer is

<h2>9.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance between them is

d =  \sqrt{ ({ - 6 - 2})^{2} +  ({ - 5 - 0})^{2}  }  \\  =  \sqrt{ ({ - 8})^{2}  + ( { - 5})^{2} }  \\  =  \sqrt{64 + 25}  \\  =  \sqrt{89}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 9.4339811

We have the final answer as

<h3>9.4 units to the nearest tenth</h3>

Hope this helps you

The height of the kite above the ground will be 108.22m.

<h3>How to get the height?</h3>

From the information, the wind makes an angle of 56° to the ground and the kite is about 73m.

Therefore, the height of the kite above the ground will be:

Tan 56° = opposite/adjacent

1.48256 = x/73

x = 73 × 1.48256

x = 108.22m
