Answer:

We have the following information :

Measure of first angle : [tex]90[/tex]°

Measure of second angle : [tex]50[/tex]°

Measure of third angle :

We know that the angles of a triangle is 180°

[tex]90 + 50 + x =180[/tex]

[tex]140 + x = 180[/tex]

moving 140 to the other side, [tex]x = 180-140[/tex]

[tex]x = 40[/tex]°

Measure of third angle is 40°
