First, i had to find the distance between points a and c, so i first found the x and y distances. 4 - 2 = 2 and 2 - (-1) = 3 now we use are ratio and divide it by the x and y distances. 2(3/4) = 1.5 and 3(3/4) = 2.25 finally, we need to add y1 to 1.5 and y2 to 2.25, to get our (x, y) of q.

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.

i think the answer is b
