Answer:

Vertical angles are always equal.

So you can set the equation up like this:

5x + 10 = 7x - 12

Subtract 5x from both sides. Then Add 12 to both sides.

22 = 2x

Divide both sides by 2.

11 = x

Answer:

m angle A = x = 30 degrees

Step-by-step explanation:

Vertical angles are equal.

So 3x - 60 = x

2x = 60

x = 30

JUST HELP ME! PLEASE!!..0o0<br><br>Applying the Pythagorean theorem, solve this triangle.​
Inessa [10]
<h3>Answer:    <u>100 ft</u>  is the hypotenuse</h3>

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

Work Shown:

a = 60 and b = 80 are the two known sides

c  is the unknown hypotenuse

Applying the pythagorean theorem gets us...

a^2 + b^2 = c^2

60^2 + 80^2 = c^2

3600 + 6400 = c^2

10,000 = c^2

c^2 = 10,000

c = sqrt(10,000)

c = 100

A quick way to see that 100 ft is the missing side is to note that a 6,8,10 right triangle scales up to 60,80,100 after multiplying all three sides by 10.

Or you could start with a 3,4,5 right triangle and multiply all three sides by 20.

10. While at the beach, Daniel buys lunch for
muminat

Answer: Each hamburger cost $3.50

Step-by-step explanation:

He spent $13 in total and bought one hot dog for $2.50  and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equation,

2.50 + 3h = 13   Now solve for x

-2.50            2.50

  3h = 10.50

 h = 3.50  

Check:

2.50 + 3(3.50) = 13

2.50 + 10.50 = 13

13=  13
