The order is C,A,B for this problem
Statement: Your question is well elaborate and has all needed data.
Answer:
B.66
Step-by-step explanation:
Perimeter =2(base+side)
2 x (13+20) = 66
6 people per group 6 people * 4 groups = 24 portions
The sum of the 3 inside angles need to equal 180.
You know 2 of the angles: 90 and 39
The third angle is 180 - 90 - 39 = 51 degrees.
Side a is given as 24
Side B = tan(39) = b/24 = 19.43 (round as needed)
Side C = cos(39) = 24/c = 30.88 (round as needed)
