Answer:
3) x = 50, vertical angles.
4) x = 20, supplementary angles
5) x = 14, complimentary angles
Step-by-step explanation:
<h3>3)</h3>
<em>vertical angles.</em>
<em>vertical angles are equal.</em>
<em>so, you can make this equation:</em>
67 = x + 17
<em>subtract 17 from both sides of the equation</em>
67 - 17 = x + 17 - 17
67 - 17 = x
50 = x
<h3>
4)</h3>
<em>supplementary angles</em>
<em>supplementary angles add up to 180</em>
<em>so, you can make this equation:</em>
7x + 40 = 180
<em>subtract 40 from both sides of the equation</em>
7x + 40 - 40 = 180 - 40
7x = 180 - 40
7x = 140
<em>divide both sides by 7</em>
7x/7 = 140/7
x = 140/7
x = 20
<h3>
5)</h3>
<em>complimentary angles</em>
<em>complimentary angles add up to 90</em>
<em>so, you can make this equation:</em>
4x + 34 = 90
<em>subtract 34 from both sides of the equation</em>
4x + 34 - 34 = 90 - 34
4x = 90 - 34
4x = 56
<em>divide both sides by 4</em>
4x/4 = 56/4
x = 56/4
x = 14
