Which of the following polynomials is a binomial?

1 answer:

5 0

<span>A binomial is a type of a polynomial which only has two terms. The name of the type of polynomial suggests that it must have only 2 terms. From the given equations in the choices, the one which has only 2 terms is the second option. Hence, the answer is letter B. </span>

What’s the correct answer??

Cosine of an angle is the adjacent leg divided by the hypotenuse.

So cos(60) = a / 12

I'm going to assume it's your last option because it's not in the picture.

9. what is the measure of QSR

Scilla [17]

<h3>Answer: C) 142 degrees</h3>

=======================================================

Explanation:

Extend segment MN such that it intersects side ST. Mark the intersection as point A. See the diagram below.

We're given that angle MNT is 72 degrees. The angle TNA is equal to 180-(angle MNT) = 180 - 72 = 108 degrees, since angles MNT and TNA add to 180.

For now, focus entirely on triangle TNA. We see from the diagram that T = 34 and we just found that N = 108. Let's find angle A

A+N+T = 180

A+108+34 = 180

A+142 = 180

A = 180-142

A = 38

So angle NAT is 38 degrees.

----------------------------

Since segment MA is an extension of MN, and because MN || SQ, this means MA is also parallel to SQ.

We found at the conclusion of the last section that angle NAT was 38 degrees. Angles QST and NAT are corresponding angles. They are congruent since MA || SQ. This makes angle QST to also be 38 degrees

----------------------------

The angles QSR and QST are a linear pair, so they are supplementary

(angle QSR) + (angle QST) = 180

angle QSR = 180 - (angle QST)

angle QSR = 180 - 38

angle QSR = 142 degrees
