The additive inverse of -5 is 5. It is the same as saying it's opposite. Just change the sign.
Answer:
<h2>x = 36°</h2>
Step-by-step explanation:
We know: the sum of the angles in any quadrilateral is 360°.
Therefore we have the equation:
108 + 108 + 2x + 2x = 360 <em>cobine like terms</em>
(108 + 108) + (2x + 2x) = 360
216 + 4x = 360 <em>subtract 216 from both sides</em>
4x = 144 <em>divide both sides by 4</em>
x = 36
Answer:
Number =108
Step-by-step explanation:
2((1/4x)-7)=(1/3x)+4
