Eric is incorrect because since the numbers he rounded 28 and 48 to are greater than 28 and 48 the answer to 28*48 will be less than the answer to 30*50 was.


30*50 = 1500


28*48 = 1344


Hope that helps!! :D

Solve the triangle. Round your answers to the nearest tenth.
butalik [34]

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)

<h3>How to determine the missing sides and angles</h3>

In this question we have a triangle with a known <em>side</em> lengths and two known <em>angle</em> measures. First, we find the missing angle by <em>Euclidean</em> geometry:

C = 180° - 94° - 23°

C = 63°

Lastly, we determine the <em>missing</em> sides by law of sines:

b = 11 \times \frac{\sin 94^{\circ}}{\sin 23^{\circ}}

b ≈ 28.084

c = 11 \times \frac{\sin 63^{\circ}}{\sin 23^{\circ}}

c ≈ 25.084

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
