Question

In triangle ABC, angle A=25 degrees, angle B=55 degrees and a= 10.73. Use the law of sines to find b. Round your answer to the nearest tenth.

Answer 1

To find side b in triangle ABC, we can use the law of sines and substitute the given values into the formula.

Step-by-step explanation:

To find side b in triangle ABC using the law of sines, we can use the formula:

1. Sin A / a = Sin B / b
2. Cross-multiply to solve for b: b = (Sin B / Sin A) * a
3. Substitute the given values: b = (Sin 55 / Sin 25) * 10.73
4. Calculate the result: b = (0.8192 / 0.4226) * 10.73 ≈ 20.8

Therefore, side b is approximately 20.8 units.
