In triangle ABC, A = 45 degrees, C = 30 degrees AB = 3. Find the side of BC.
September 12, 2021 | education
| To determine the lengths of the sides of a triangle, we use the theorem of sines.
ВС / SinВАС = BA / SinBCA.
ВС / Sin45 = BA / Sin30.
ВС = Sin45 * (BA / Sin30).
BC = (√2 / 2) * (3 / (1/2).
BC = 3 * √2 cm.
Answer: The BC side is 3 * √2 cm.
