STEP 1: Convert Input(s) to Base Unit

Side B of Triangle: 14 Meter --> 14 Meter No Conversion Required
Angle A of Triangle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Angle B of Triangle: 40 Degree --> 0.698131700797601 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_a = S_b*sin(∠A)/sin(∠B) --> 14*sin(0.5235987755982)/sin(0.698131700797601)

Evaluating ... ...

S_a = 10.8900667880246

STEP 3: Convert Result to Output's Unit

10.8900667880246 Meter --> No Conversion Required

FINAL ANSWER

10.8900667880246 ≈ 10.89007 Meter <-- Side A of Triangle
