Find the distance between the points (3 4) and (4 3)

Usimov [2.4K]

Answer:

$\sqrt{2}$ or 1.414213

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

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

d = distance

$(x_{1}, y_{1})$ = coordinates of the first point

$(x_{2}, y_{2})$ = coordinates of the second point

Find the value of X<br> please help!

denis23 [38]

Answer:

Step-by-step explanation:

So the first thing to do is get the number of angles inside this pentagon, which is 540 degrees. One way to do this is that you know a pentagon is formed of 3 triangles and since there are 180 degrees in a triangle, 3x180=540

Then it is algebra

540=91+125+92+(3x-5)+(4x-8)

Simplify what you can and collect like terms

540=308+3x-5+4x-8

540=308+7x-13

Then move everything over to the one side so that the variable is isolated

540-308+13=7x

245=7x

242/7=x

35=x
