Answer: 106
Step-by-step explanation: you have a total of 180 degrees in there, so you only gotta find the unknown value of the other side so you do 180 - 64 which is 116. then you see that in order to get 116 you gotta add it times ten which you are gonna subtract by 10 which is 106, and 106 will be your answer.
The found value of x is 106°
We know that the measures of the sum of an inner triangle are equal to 180. So, to solve this question, we will just: add the like terms with equality equal to 180.
Finally, let's calculate as a first degree equation, just: isolating x and dividing both sides.
Therefore, the answer will be x = 106°
