All angles in a triangle add up to 180 degrees, so if you have a right triangle, one angle is 90 and the other is 70, so add 90+70= 160
Then 180-160=20
Your answer would be 20.
Answer:
20 degrees
Step-by-step explanation:
Since all three angles of a triangle have to add up to 180 degrees and we know two of the angles, 90 degrees and 70 degrees
90 + 70 = 160
180 - 160 = 20
