Vertical angles are always congruent. Therefore you must set them equal to each other. If we set 2x+20=3x+15 we can do the math like so

2x+20=3x+15
-15 | -15
2x+5 | 3x
-2x | -2x
5 | X

Now to check the answer 2*5+20=30
3*5+20=30
30=30


X=5 is the correct answer. Hope this helped and happy geometry!

Answer:

x = 5°

Step-by-step explanation:

2x+20 = 3x +15 —> Opposite angles

3x - 2x = 20 - 15

x = 5

I hope I helped you^_^

What is the distance between the points (2, -3) and (-6, 4) on the coordinate
VikaD [51]

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (<em>x₁, y₁</em>) and let (-6, 4) be (<em>x₂, y₂</em>). Substitute:

d=\sqrt{(-6-2)^2+(4-(-3))^2}

Simplify:

d=\sqrt{(-8)^2+(7)^2}

Evaluate:

d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}

Our answer is C.

The sum of two numbers is -36. Their difference is 68
trasher [3.6K]

Answer:

Step-by-step explanation:

Let the numbers be x and y

x + y = -36........(1)

x - y = 68..........(2)

Adding (1) and (2)

2x = 32

x = 32/2

x = 16

And x + y = -36....(1)

16 + y = -36

y = -36 - 16

y = -52

The number are 16 and -52
