Hi please help thank you! =D

X=125

Step-by-step explanation:

So we know that angle x plus the other unidentified angle would equal 180 so in order to find x we need to identify the other angle inside the triangle.

To do this simply add 50 and 75 to get 125. Then subtract 125 from 180 because all angles in a triangle total at 180.

Now that we know that angle is 55 we simply subtract that from 180 because the total of that angle and x should equal 180

10% of increase is the final answer! : )
