Answer 1

 

ANSWER: 52

Step-by-step explanation:

Given number => 1104

Nearest square number => 1156

Answer 2

Answer:

To convert angle of bearing to degrees of a standard angle, subtract the bearing angle from 90°. If you end up with a negative answer, add 360°, and if your answer is greater than 360°, subtract 360° from it. For a bearing angle of 180°, the standard angle would be 270°.
