yes. the sum is 180
Explanation
Step 1
Two angles are called supplementary when their measures add up to 180 degrees.
then ,
if 2 angles are right angles
[tex]\text{angle}_1=angle_2=90[/tex][tex]\text{angle}_1+angle_2=90+90=180[/tex]
so, angles are supplementary
because the sum is always 180 degrees
