Since it's a right triangle, one of the other angles is \(\displaystyle{90}^{\circ}\). The sum of all angles in a triangle is always 180. Let the third angle be x:
\(20+90+x=180\)
\(x=180-90-20\)
\(\displaystyle{x}={70}^{\circ}\)
Answer:
\(\displaystyle{90}^{\circ}{\quad\text{and}\quad}{70}^{\circ}\)
