Step 1 :We are given that the lengths of side a is 100 m, and the measures of angles A and C are \(39^{\circ} 54^{\prime}\) and \(27^{\circ} 26^{\prime}\) respectively.
Step 2 :We know that the sum of the angles in a triangle is \(180^{\circ}\). So, we can find the measure of angle B by subtracting the measures of angles A and C from \(180^{\circ}\).
Step 3 :Converting the given angles to decimal form, we get A = 39.9 and C = 27.433333333333334.
Step 4 :Subtracting these from 180, we get B = \(180 - 39.9 - 27.433333333333334 = 112.66666666666666^{\circ}\).
Step 5 :Next, we can use the law of sines to find the length of side b. The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.
Step 6 :First, we convert the angles from degrees to radians. We get A_rad = 0.6963863715457375, B_rad = 1.9664042905802779, and C_rad = 0.4788019914637777.
Step 7 :Then, we use the law of sines to find b: \(b = a \cdot \frac{\sin(B)}{\sin(A)}\). Substituting the given values, we get \(b = 100 \cdot \frac{\sin(1.9664042905802779)}{\sin(0.6963863715457375)} = 144\).
Step 8 :So, the length of side b is \(\boxed{144}\) meters.
