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)​

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

a) 7x=7

step-by-step explanation:

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
