Answer:
<h2>x = 7</h2>
Step-by-step explanation:
The angles (6x - 7) and (4x + 7) are the vertical angles.
The vertical angles are congruent, therefore have the same measure.
We have equation:
6x - 7 = 4x + 7 <em>subtract 4x from both sides</em>
<em>6x - 2x - 7 = 4x - 2x + 7</em>
2x - 7 = 7 <em>add 7 to both sides</em>
<em>2x - 7 + 7 = 7 + 7</em>
2x = 14 <em>divide both sides by 2</em>
<em>2x : 2 = 14 : 2</em>
x = 7

Answer:
3
Step-by-step explanation:
first you would solve 2^3. It is 2x2x2 which is 8. Then you do 20-8 which equals 12. Then to finish it off you do 12/4 which is 3
