Answer:
1.) 22
2.) 122
Explanation:
For the first 1, the degrees in a right angle is 90 degrees and if you already have 68 you have to subtract 90-68= 22.
For the second one, an obtuse angle is 180 degrees. If you already have 58 degrees so you have to subtract 180-58= 122 degrees.
The reason you are subtracting is to find the remaining numbers.
