To find the length of side a, we can use the formula for the area of a triangle:
Area = (1/2) * base * height
In this case, side c is the base and side a is the height. We are given that the area is 92.5 km^2, side c is 16 km, and angle C is 73 degrees.
So, we can write the equation as:
92.5 = (1/2) * 16 * a
Rearranging the equation to solve for a:
a = (2 * 92.5) / 16
a ≈ 11.56
Therefore, the length of side a to the nearest kilometer is 12 km.
if the area of △ABC=92.5 Km^2, ∠C=73 degrees, abd b=16 km, then what is the length of a to the nearest km
