Since the proof for x = 30, the missing reason in step 3 is known to be angle addition postulate.
<h3>What is angle addition postulate?</h3>
This is known to be the law that state that when one put two or more angles side by side making them to share a common vertex and also an arm between the both pair of angles, then the sum of those angles will then be the same with the total sum of the resulting angle.
Since T = is the interior of straight angle ∠VRS.
m∠VRS = 180° ( is a straight line angle)
So, based on the angle addition postulate says that:
m∠TRS + m∠TRV = 180°.
Therefore, since the proof for x = 30, the missing reason in step 3 is angle addition postulate.
