Please help me answer this

Ronch [10]

Answer:

10.77

Step-by-step explanation:

by using Pythagoras theorem we can find the distance between the points,

so...

distance between the points, which is the hypotenuse will be xy

difference between the y coordinates will be dy

difference between the x coordinates will be dx

according to pythagoras theorem,

$xy^{2} = dx^{2} + dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77$

Find the value of x.

faust18 [17]

Answer:

7 sqrt(3) =x

Step-by-step explanation:

We know that sin 60 = opposite / hypotenuse

sin 60 = x/14

Multiply both sides by 14

14 sin 60 = x

14 * (sqrt(3)/2) =x

7 sqrt(3) =x
