(Need help pleas!!) Find the perimeter of the triangle on the coordinate plane with vertices at coordinates (1,3),(3,-3) and (1,-3). Use the distance formula when necessary. Randy answer to the nearest whole number, enter that number.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

x = 12

y = 1

for the points!
