I would have guessed point S is (3,0).

Choose all the angles which are adjacent to < 3<br> Select all that apply

morpeh [17]

Answer:

A and B

Step-by-step explanation:

Adjacent angles are angles that share a common vertex

More specifically adjacent angles are next to each other.

The two angles that are next to ∠3 are ∠4 and ∠2 therefore the correct answer would be A and B

AB is perpendicular to CD. If the slope of AB is 2/5, what is the slope of CD?

alekssr [168]

Given a slope $m$ , the slope $m'$ of a line perpendicular to $m$ is the opposite of the inverse of $m$

In other words:

$mm' = -1 \iff m' = -\dfrac{1}{m}$

So, the slope of CD is -5/2.

What is the answer to the questions

loris [4]

<h3>Answer: x = 40</h3>

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

Work Shown:

A+B+C = 180 ..... three angles of any triangle add to 180

(2x+10)+(x)+(2x-30) = 180

5x-20 = 180

5x = 180+20 .... adding 20 to both sides

5x = 200

x = 200/5 ... dividing both sides by 5

x = 40

This is the measure of angle B

We can stop here.

If you need to know the values of the other angles, then,

angle A = 2x+10 = 2*40+10 = 90
angle C = 2x-30 = 2*40-30 = 50

Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.
