Step-by-step explanation:

7 1/5 × 49 7/5 = 49

convert mixed numbers into improper fractions (whole number × denominator + numerator)

7 × 5 + 1 = 36

49 × 5 + 7 = 252

36/5 × 252/5 = 49

All fractions must have a common denominator

49 × 5 = 245

36/5 × 252/5 = 245/5

Add numerators

36 + 252 = 288

288/5 = 245/5

57 3/5 = 49

These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?

Law of Sines , in any triangle we have
a/sin A = b/sin B = c/sin c

4/sin20 = AC/sin80 = AB/sin80

now we can solve AC

4/sin20 = AC/sin80
AC = 4 (sin80)/ sin20
AC = 4(0.98) / (0.34)
AC = 3.92 / 0.34
AC = 11.52

answer

C.11.52 centimeters
