X = 140 because that is a 180 degree triangle and I subtracted by 40 and that’s how I got 140

Answer:

140

Step-by-step explanation:

First you want to find the total angle that there is. This angle would be 180°.

Now you subtract all known values from this. So you would have to do

180° - 40°

This gets you 140°. Since there are no another angles, this is X°
