Answer:
The possible values for ∠V is 81.2° and 98.8°
Explanation:
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°. Find all possible values of ∠V, to the nearest 10th of a degree.
We solve the above question using Sine rule
Sine rule
= u/sin U = v/sin V
In ΔUVW, v = 8.1 cm, u = 7.6 cm and ∠U=68°
Hence:
7.6/sin 68° = 8.1/sin V
Cross Multiply
7.6 × sin V = sin 68° × 8.1
sin V = sin 68° × 8.1/7.6
V = arc sin ( sin 68° × 8.1/7.6)
V = arc sin (0.99)
V = 81.18°
Another value for V = 180° - 81.18°
= 98.82°
Therefore, the possible values for ∠V approximately to the nearest tenth of a degree is 81.2° and 98.8°
