Solution
Step 1 ：Given that $A=43.5^{\circ}$, $a=8.8$ m, and $b=10.5$ m, we can use the Law of Sines to find the other angles and sides.
Step 2 ：First, calculate angle B using the formula: $B = \sin^{-1}\left(\frac{b \cdot \sin(A)}{a}\right)$
Step 3 ：Substitute the given values into the formula to get $B = \sin^{-1}\left(\frac{10.5 \cdot \sin(43.5)}{8.8}\right)$, which gives $B = 55.2^{\circ}$
Step 4 ：Next, calculate angle C using the formula: $C = 180 - A - B$
Step 5 ：Substitute the given values into the formula to get $C = 180 - 43.5 - 55.2$, which gives $C = 81.3^{\circ}$
Step 6 ：Finally, calculate side c using the formula: $c = a \cdot \sin(C) / \sin(A)$
Step 7 ：Substitute the given values into the formula to get $c = 8.8 \cdot \sin(81.3) / \sin(43.5)$, which gives $c = 12.6$ m
Step 8 ：Final Answer: The measurements for the remaining angles $B$ and $C$ and side $C$ are as follows. \(\mathrm{m} \angle \mathrm{B}= \boxed{55.2}^{\circ}\), \(\mathrm{m} \angle \mathrm{C}= \boxed{81.3}^{\circ}\), The length of side $\mathrm{c}= \boxed{12.6} \mathrm{~m}$
