Answer: <em>60°</em>
<em>First let's notice how all of the angles are on a straight line</em>
<em>We know that straight lines must equal to </em><em>180°</em>
<em>Let's take our given angles and add the together </em>
<em>63°+26°+31°=120°</em>
<em>Now we take 180° and subtract is from 120° to give us angle x</em>
<em>180°-120°=60°</em>
<u><em>3 / 3/4 </em></u>
3/1 x 4/3 = <u><em></em></u><em><u>4</u></em><em>
