Question

A triangle is graphed in the coordinate plane. The vertices of the triangle have coordinates (–3, 3), (5, 3), and (5, –3).

What is the perimeter of the triangle?


A. 22
B. 24
C. 28
D. 30

Answer 1

your simply going to have to apply the distance formula 3 times around ....

Answer 2

or, if they line up nicely, youll only have to use it once

Answer 3

yeah, plotting them shows that 2 sides are simple enough to assess. the third side is a pythagorean process.

Answer 4

Ok so what is the equation or solution that I use?

Answer 5

well the 2 sides are simply counting .... the third side you can use the pythagorean thrm for:

a^2 + b^2 = c^2, and solve for x

Answer 6

*solve for c .... they had to put that key right next to the x :)

Answer 7

Thank you

Answer 8

good luck

Answer 9

if you want to check your solution ... feel free to post it

Answer 10

ok hold on

Answer 11

x=c over b ??

Answer 12

the 2 sides (a and b) are simply counting .... the third side you can use the pythagorean thrm for:

a^2 + b^2 = c^2, and solve for c (the hypotenuse of a rt triangle)

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

Answer 13

a2 + b2 = ??

Answer 14

Or give the solution to the problem so I can solve for x.

Answer 15

there is no x to solve ....

Answer 16

what do you get for the 2 sides, a and b?
