Answer:
Step-by-step explanation:
we are given that one angle is 40 degrees. The right angle below that is 90 degrees. Right angles will always equal 90 degrees. with the two angles how do we solve. Triangles no matter what will always be 180 degrees so,
40+90+x=180
130+x=180
-130 -130
x=50 degrees
