D. 36.8 in\(^2\)

Find the length of side \(a\).

A. 27
B. 4
C. 43
D. 23

Answer :

Final answer:

To find the area of triangle ABC, use the formula Area = (1/2) * b * c * sin(A) where A is the given angle and b and c are the given sides. Convert the angle from degrees to radians if needed and compute the area using the formula.

Explanation:

To find the area of triangle ABC, we can use the formula:

Area = (1/2) * b * c * sin(A)

Given the values:

A = 34.9°

b = 10.2 in

c = 8.8 in

Plugging these values into the formula, we have:

Area = (1/2) * 10.2 * 8.8 * sin(34.9°)

Note: sin function requires angles to be in radians, so we need to convert degrees to radians.

Converting A to radians: A = 34.9 * 3.14159 / 180

Area = (1/2) * 10.2 * 8.8 * sin(34.9 * 3.14159 / 180)

Calculating the area, we get:

Area ≈ 23.7 in2
