In \( \triangle ABC \), given:

- \( C = 96.2^\circ \)
- \( b = 11.2 \, \text{cm} \)
- \( c = 39.4 \, \text{cm} \)

Solve the triangle completely.

Answer :

Final answer:

To solve △ABC, calculate the length of side 'a' using the law of cosines and then calculate the angles A and B using the law of sines. Substituting the given values into the formula will provide the solutions.

Explanation:

To solve the triangle △ABC completely, first, use the law of cosines to calculate the length of the remaining side 'a'. The formula for the law of cosines is a²=b²+c²-2bcCos(γ), where γ is the angle C. Substituting the given values: a² = (11.2cm)²+(39.4cm)²-2*(11.2cm)*(39.4cm)*Cos(96.2°). Solve this to find the value of 'a'.

Next, use the law of sines to calculate the remaining angles A and B. The formula for the law of sines is a/Sin(A)=b/Sin(B)=c/Sin(C). Use these formulas to solve for angles A and B.
