Answer:
Step-by-step explanation:
To start with a = 12 (given)
Tan(50) = b / 12
Tan(50) = 1.192
1.192 = b / 12 Multiply both sides by 12
1.192 * 12 = b
b = 14.301
=================
Cos(50) = 12/c
Cos(50) = 0.4628
0.4628 = 12 / c Multiply both sides by c
0.4628 * c = 12 Divide by 0.4628
c = 12/ 0.4628
c = 18.67
