Question

What is the value of x? Enter your answer in the box.

Answer 1

19

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 2

19

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
