Step-by-step explanation:

Which of the following shows the polynomial below written in descending<br> order?
Vladimir79 [104]

Answer:

A. 4x¹² + 9x⁷ + 3x³ -x

Step-by-step explanation:

Hi!

<em>==================================================================</em>

To write a polynomial in descending order, we write the terms with higher degrees, or exponents, first.

3x³ + 9x⁷ -x + 4x¹²

4x¹² has the highest degree, so it is written as the first term.

⇒4x¹²

9x⁷ has the next highest degree, so it is written next.

⇒4x¹² + 9x⁷

3x³ has the next highest degree, so it is written next.

⇒4x¹² + 9x⁷ + 3x³

-x has the lowest degree, so it is written last.

⇒4x¹² + 9x⁷ + 3x³ -x

<u>4x¹² + 9x⁷ + 3x³ -x</u>

<em>==================================================================</em>

<em>Hope I Helped, Feel free to ask any questions to clarify :)</em>

<em>Have a great day!</em>

Can anyone help me solve this??
labwork [276]

here is your answer mate.

in triangle ABC

angle ABC + angleBAC + angleACB = 180 Degrees. (angle sum property of triangle)

90 + 58 + angle ACB = 180 degree.

148 + angle ACB = 180 degree.

angle ACB = 180 - 148

angle ACB = 32 degree

the angle of elevation is 32 degrees
