Answer:

D) 2x^2 + 11x^3 + 12x^2 - 10x - 8

Step-by-step explanation:

you multiply each term of the first expression with each term of the second expression and add all the terms

so start with x^2 * 2x^2 = 2x^4

x^2 * 3x = 3x^3

x^2 * -4 = -4x^2

4x * 2x^2 = 8x^3

at this point it's clear that the correct answer is D but we can continue

4x * 3x = 12x^2

4x * -4 = -16x

4x^2

-8

by adding

2x^2 + 11x^3 + 12x^2 - 10x - 8

Answer:

<h2>The obtuse angle is 120°.</h2><h2>The acute angle is 60°.</h2>

Step-by-step explanation:

This problem is about two crossing line, when that happens, we have 4 angles, two acute and two obtuse, where adjacent angles are supplementary and vertical angles are equal.

We can form the expression

$A = \frac{O}{2}$

Where $A$ is an acute angle and $O$ is an obtuse angle.}

Using all the given information, we have

$O + \frac{O}{2}=180\°$

Solving for $O$ , we have

$\frac{3O}{2}=180\\ O=120\°$

Therefore, the obtuse angle is 120°, which means the acute angle is 60°, because they are supplementary angles, as we said befor.
