Given line segment AB, the coordinates of A are (3,-5) and the coordinates midpoint are (5,-1), what are the coordinates for B?
dsp73

Answer:

<h3>           B(7, 3)</h3>

Step-by-step explanation:

Point P(5, -1) being the midpoint of AB means that  x_P-x_A=x_B-x_P

5-3=x_B-5\\\\2+5=x_B\\\\x_B=7

and   y_P-y_A=y_B-y_P

-1-(-5)=y_B-(-1)\\\\-1+5=y_B+1\\\\y_B=3

Top side is 6 just couldn’t fit in picture
irina1246 [14]

Answer: 6

Step-by-step explanation:

Use the pythagorean theorem to find z first.

c^2=a^2+b^2\\c=\sqrt{a^2+b^2}

a = 12

b = 6

c = z

c=\sqrt{(12)^2+(6)^2}\\ c=\sqrt{144+36}\\ c=\sqrt{180} \\c=13.4

z is greater than a and b
