Answer:
The difference is 4 degrees
Step-by-step explanation:
If its difficult for you to subtract negatives just switch them to a positive 1 and 5 now subtract 1 from 5=4 and because the measure being used is degrees the final answer would be 4 degrees.
The permutation and the combination would be ^{15}P_4= 32760 and ^{15}C_4 = 1365.
<h3>What is the formula used for permutation and combination?</h3>
To calculate permutation
Given; n = 15, k = r = 4
Therefore, ^{15}P_4 = 32760
