Answer:

The answer is

<h3>4 \sqrt{2}   \: \:  \: or \:  \:  5.656 \:  \:  \: units</h3>

Step-by-step explanation:

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

<h3>d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\</h3>

where

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

From the question the points are

(8,-3) and (4,-7)

The distance between them is

<h3>d =  \sqrt{ ({8 - 4})^{2}  +  ({ - 3 + 7})^{2} }  \\  =  \sqrt{ ({4})^{2} + ( { - 4})^{2}  }  \\  =  \sqrt{16 + 16}  \\  =  \sqrt{32}</h3>

We have the final answer as

<h3>4 \sqrt{2}   \: \:  \: or \:  \:  5.656 \:  \:  \: units</h3>

Hope this helps you

PLS HELP IM BEGGING U
expeople1 [14]

Answer:

answer is 57.

Step-by-step explanation:

Given

m<6= x - 8

m<7 = 2x - 7

We know

<6 + <7 = 180° [ being linear pair ]

x - 8 + 2x - 7 = 180°

3x - 15 = 180°

3x = 180° + 15°

3x = 195°

x = 195° / 3

x = 65°

Now

m<6= x - 8 = 65° - 8° = 57°

hope it helps :)
