Answer:

Step-by-step explanation:

Since these two are vertical angles, their measure must be equal. Therefore:

$3x-3=6(x-10) \\\\3x-3=6x-60 \\\\3x+57=6x \\\\3x=57 \\\\x=19^{\circ}$

Hope this helps!

Answer:

Step-by-step explanation:

The two angles are vertically opposite angles, so they are equal.

3x - 3 = 6 (x - 10)

3x - 3 = 6x - 60

3x - 6x = - 60 + 3

-3x = -57

x = -57/-3

x = 19

In the image, point A marks the center of the circle. Which two lengths must form a ratio of 2:1?

aksik [14]

Draw a diameter through the center of the circle. Any radius of this circle is 1/2 the length of the diameter. Thus, if we divide the diameter into two equal parts, we have two lengths that form the ratio 2:1, where 2 represents the diameter and 1 the radius.
