Answer:
68 degrees
Explanation:
If they tell you it's a right triangle, you automatically know one angle is 90 degrees. Since they've told you another angle is 22 degrees, the total number of degrees you have out of 180 is 112. Meaning, whatever's left is your third angle.
180 - 90 - 22
= 180 - 112
= 68 degrees
