Miguel plotted the three vertices of a triangle. Two of the vertices are shown on the grid below. у 3 2 1 0 1 2 3 4 5 Which of these could be all three vertices of Miguel's triangle? Select all that apply. a (1, 1), (1,3), (4,2) O (1, 1), (3, 1), (2, 4) C (1,3), (3,5), (4,2) d (3, 1), (2, 1), (4,2) e (3, 1), (2, 4), (3,5)​

55? i think maybe

step-by-step explanation:

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.
