Answer:

<h2>first blank:</h2><h2>c=sqrt(a^2+b^2)</h2><h2>second blank:</h2><h2>c=sqrt((8-2)^2+(-5-3)^2)</h2><h2 />

Step-by-step explanation:

c^2=a^2+b^2

sqrt(c^2)=sqrt(a^2+b^2)

c=sqrt(a^2+b^2)

c=sqrt((x2-x1)^2+(y2-y1)^2)

c=sqrt((8-2)^2+(-5-3)^2)

Step-by-step explanation:

A person 6 feet tall standing 18 feet away a lamppost cast a 9 foot shadow.

than move 4 feet than total distance is 22 feet  

According to trigonometry rule make 30 degree angle

tan\left ( 30\ \right )^{o}=\frac{p}{b}

\left ( \frac{1}{\sqrt{3}} \right )=\left ( \frac{x}{18+4} \right )

or

x\sqrt{3}=22

than

x=\frac{22}{\sqrt{3}}

The midpoint of AB is M(1,4).if the coordinates of A are (-3,-6),what are the coordinates of B
boyakko [2]

midpoint of AB (M)=(1,4)=(x,y)

COOrdinates of A=(-3,-6)=(X1,Y1)

coordinates of B=?

using midpoint formula,

X=(X1+X2/2)

or,1=(-3+X2/2)

or,2=-3+X2

or,2+3=X2

5=X2

<h2> And</h2>

Y=(Y1+Y2/2)

or,4=(-6+Y2/2)

or,4×2=-6+Y2

or,8+6=Y2

14=Y2

so,co-ordinates of B are(5,14).

plz mark me brainliest.
