Which set of ordered pairs could be generated by an exponential function? A (-1, -1/2), (0,0), (1, 1/2), (2,1) B (-1,-1), (0,0), (1,1), (2,8) C (-1,1/2), (0,1), (1,2), (2,4) D (-1,1), (0,0), (1,1), (2,4)

step-by-step explanation:

sry but any answer choices

false

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.
