Answer:
20%
Step-by-step explanation:
All angles of a triangle add up to 180 degrees.
A right triangle has one right angle, which means an angle is 90 degrees.
If another is 70 degrees then we already know two of them. Add them up to get 160 degrees. Then subtract that from 180 degrees to get 20 degrees. Hope it helps!
