To solve this triangle, we are given the following:

• Angle $B = 137.7^\circ$
• Side $c = 7.325$
• Side $b = 14.224$

We will use the Law of Sines and the Law of Cosines to determine the remaining unknowns: angle $A$, angle $C$, and side $a$.

Step 1: Check for possible solutions using the Law of Sines

We know the following relationships for the Law of Sines:

$\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}$

First, we can solve for angle $A$ using the Law of Sines. Since we have $B$, $b$, and $c$, we can use:

$\frac{b}{\sin B} = \frac{c}{\sin C}$

Substitute the values we know:

$\frac{14.224}{\sin 137.7^\circ} = \frac{7.325}{\sin C}$

Now, solve for $\sin C$:

$\sin C = \frac{7.325 \times \sin 137.7^\circ}{14.224}$

Step 2: Solve for $C$ and $A$

After finding $C$, we can determine $A$ because:

$A = 180^\circ - B - C$

Then, we can use the Law of Sines again to find $a$:

$\frac{a}{\sin A} = \frac{b}{\sin B}$

I'll calculate all these values now. math

Given values

B = 137.7 # in degrees b = 14.224 # side b c = 7.325 # side c

Convert B to radians for calculations

B_rad = math.radians(B)

Calculate sin of B

sin_B = math.sin(B_rad)

Calculate sin C using the Law of Sines

sin_C = (c * sin_B) / b

Solve for angle C using arcsin (inverse of sin)

C_rad = math.asin(sin_C)

Convert C back to degrees

C = math.degrees(C_rad)

Calculate angle A

A = 180 - B - C

Solve for side a using the Law of Sines

sin_A = math.sin(math.radians(A)) a = (b * sin_A) / sin_B

Round to the required precision

A_rounded = round(A, 1) C_rounded = round(C, 1) a_rounded = round(a, 3)

(A_rounded, C_rounded, a_rounded)The triangle has the following measurements:

• Angle $A = 22.0^\circ$
• Angle $C = 20.3^\circ$
• Side $a = 7.925$ (rounded to the nearest thousandth)

Conclusion:

• There is only one possible solution for the triangle based on the given information.

Tip: When solving non-right triangles, always check the possible cases with the Law of Sines first (one or two solutions), and use the Law of Cosines for triangles with more complex configurations.
