WebNov 17, 2024 · We can use the Law of Sines to find the other opposite angle B, then find the third angle C by subtracting A and B from 180 ∘, then use the law of sines to find the third side c. By the Law of Sines, we have sinB b = sinA a ⇒ sin B = b sinA a = 30sin 25 ∘ 18 ⇒ sinB = 0.7044 . Using the sin − 1 button on a calculator gives B = 44.8 ∘.
