Answer:

A. 50

Step-by-step explanation:

Sum of interior angles of a triangle is always =180 °

Since this is a right triangle, therefore we know that one angle of the triangle measures 90°

Therefor sum of other two angles has to be =[tex]180\°-90\°=90\°[/tex]

One angle measures = 40°

Therefore the missing angle [tex]y=90\°-40\°=50\°[/tex]

[tex]y=50\°[/tex]
