<span>For problem 8:
sin A/a sinB/b = sinC/c
so sin50/15 = sinB/12
0.766/15 =sinB/12
0.051066 = sin B/12
sin B = 0.6128
B = 37.79 degrees
sum of angles must equal 180 deg therefore C = 180-50-37.79 = 92.21 degrees and .766/15 = sin92.21/c
.051066= 0.99925/c
c = .99925/0.051066 = 19.567
Problems 9 and 10 can also be done with the same method as problem 8.

Answer:
Step-by-step explanation:
5x^2 +3 = 83 . . . . given
5x^2 = 80 . . . . . . .subtract 3
x^2 = 16 . . . . . . . . .divide by 5
x = ±√16 = ±4 . . . take the square root
The smaller value of x is -4; the larger value, +4.
Number 2 is 93 cm as you get the area of each shape inside of the net and add them to get 93 cm
