Answer:

x = 20

Step-by-step explanation:

The angles that are marked are called "vertical angles" (I think of a pair of scissors) The two angles are equal to each other. (They get bigger or smaller together, like a pair of scissors)

So, set them equal to each other and solve.

3x + 50 = 6x - 10

SUBTRACT 3x from both sides.

50 = 3x - 10

ADD 10 to both sides.

60 = 3x

DIVIDE both sides by 3.

20 = x

Solve for the proportion. x+2/5=6/15

Lelechka [254]

For this case we must solve the following proportion:

$\frac {x + 2} {5} = \frac {6} {15}$

Multiplying by 5 on both sides of the equation we have:

$x + 2 = \frac {6 * 5} {15}\\x + 2 = \frac {30} {15}\\x + 2 = 2$

Subtracting 2 from both sides of the equation:

$x = 2-2\\x = 0$

ANswer:

$x = 0$
