Answer:
40°
Step-by-step explanation:
A whole triangle's measurements should always add up to 180° no less or over. Therefore with this problem you can subtract 180 with the 2 given points.
180 - 90 - 50 = 40
Hope this helps!
Since we know that a triangle contains 180°
so we can make an equation
[tex]x+90+50=180[/tex]
solve it and we get
[tex]x=40[/tex]°
