7x8 - 2x + 15x6 + 1 Is this a polynomial? (If yes, answer the rest of the questions)
How many terms?
I
What are the coefficients of each of the terms in this polynomial?
What is the degree of the polynomial?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

1/800 is the right answer

r and t.

both are 64 degrees.
