Answer:
1. 22 degrees
2. 122 degrees
3. Angle 1 is supplementary to angle 6
Explanation:
1. It is supposed to be a right angle which means that 90. So, to find GHK you must do 90 - 68 = 22. I don't understand why it is incorrect but, I can promise you that is the correct answer
2. A straight angle is 180 degrees. So, you would subtract 180 - 58 = 122.
Therefore, your answer for 2 would not be 112 degrees it would in fact be 122 degrees.
