Answer: 38° and 52°
Steps:
x + 38° = 90°
x = 90° - 38°
x = 52°
90° - 52° = 38°
The answer to your question is 136, pretty self explanatory
The absolute value sign makes it so that k+7 could be either -3 or +3 and the result would still be 3. This means there are two possible answers for k. The one that makes k+7=-3 and the one that makes k+7=+3. Just solve these two equations:
k+7=-3
k=-3-7
k=-10
k+7=3
k=3-7
k=-4
So the possible answers are -4 and -10. B is the correct choice.
