Answer:

53

Explanation:


(sin(56))/(78.6) = (sin(90))/(ab) \\ \\ absin(56) = sin(90) * 78.6 \\ \\ ab = (sin(90) * 78.6)/(sin(56)) \\ ab = 94.8 \\ \\ {x}^(2) + {78.6}^(2) = {94.8}^(2) \\ {x}^(2) = {94.8}^(2) - {78.6}^(2) \\ {x}^(2) = 8987.04 - 6177.96 \\ {x}^(2) = 2809.08 \\ x = √(2809.08) \\ x = 53
