Answer:
<h3>
720 different ways</h3>
Step-by-step explanation:
Permutation has to do with arrangement. If r objevt selected from n pool of objects are to be arranged in a straight line, this can be done in nPr number of ways.
nPr = n!/(n-r)!
If 5 people are to be chosen and arranged in a straight line, if there are 6 people to choose from, this can be done in 6P5 numbe of ways.
6P5 = 6!/(6-5)!
6P5 = 6!/1!
6P5 = 6*5*4*3*2*1
6P5 = 720 different ways
It should be 100 because it has to add up to 180 and 50+30=80 so the third angle must be 100
Answer: For C and D you put the same answer but its D. P/ 12 which stands for p divided by 12.
Step-by-step explanation:
Answer:
