Use the polynomial to answer the question below: 5x^3– 2x – 6 a. What is the coefficient of the second term?
b. What is the variable of the first term?
c. What is the exponent in the second term?
d. What is the constant?
Does this classify as a monomial, binomial, or trinomial?

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.

answer: it is a.,b.,d.
