Final answer:
To find the length of side a in triangle ABC, use the Law of Sines.
Step-by-step explanation:
To find the length of side a in triangle ABC, we can use the Law of Sines. The Law of Sines states that the ratio of a side length to the sine of its opposite angle is constant for all sides and angles in a triangle. In this case, we have side b = 620 cm, angle C = 106°, and angle A = 48°. We can set up the following proportion:
a / sin(A) = b / sin(B)
Substituting the given values, we get:
a / sin(48°) = 620 / sin(106°)
Solving for a, we find the length of side a to be approximately 719 cm (rounded to the nearest centimeter).
