Vertical angles are the same measurement and are opposite each other.

Angle 3 is opposite angle 1 and would also be 130 degrees.

Answer:

∠3

Step-by-step explanation:

See attachment.

As we can see, ∠1 and ∠3 lie opposite each other, while ∠2 and ∠4 lie opposite each other. In other words, ∠1 and ∠3 are vertical angles; by definition, then, ∠1 = ∠3.

We already know that ∠1 = 130°, so that must mean ∠3 also equals 130°.

The answer is thus ∠3.

Graph the line by plotting y=x+8​
Zarrin [17]

The equation y = x + 8 uses the slope intercept form

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

In this case

y = 1x + 8

m = 1

y = x + 8

b = 8 OR y-intercept of this line is (0, 8)

You can plot the point (0, 8) on a graph. Then to find the next point you will rise up 1 and over right 1 (this is the slope). You can find another point after that by going down one and left one from the point (0, 8)

The graph should look like the one in the image below

Hope this helped! Let me know if you have any further questions

normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
