yes. the sum is 180
Step-by-step explanation
Step 1
Two angles are called supplementary when their measures add up to 180 degrees.
then ,
if 2 angles are right angles
![\text{angle}_1=angle_2=90](https://img.qammunity.org/2023/formulas/mathematics/college/gl1d86dxq4oik2xm9loob5u5p5e1retnm3.png)
![\text{angle}_1+angle_2=90+90=180](https://img.qammunity.org/2023/formulas/mathematics/college/b42lpjx2b8uvpkh6whuldspfuvem1m5viq.png)
so, angles are supplementary
because the sum is always 180 degrees
I hope this helps you
