INDEPENDENT WORK: (This will be scored as a 4-point Regents Question) 10 and b(x) = x + 2, determine
Given a(x) = x+ + 2x3 + 4x
a(x)
b(x)
in the form q(x)+r(x)/b(x)

c

step-by-step explanation:

c

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.
