Answer:
Explanation:
The angle adjacent to the 106 degree angle is 180 degrees - 106 degrees, or 74 degrees. Next, the adjacent angle to the 145 degree angle is 35 degrees; in other words, the two bottom angles of this triangle are 35 degrees and 35 degrees. That means that a 35 degree angle is vertical angle to x, and so x is also 35 degrees.
The sum of the three interior angles is 35 degrees + 74 degrees and
