The length of BC is 2.30

Explanation:

It is given that AB = 3 and ∠A = 50°

To find the length of BC, let us use the sine formula.

The formula is given by

$\sin \theta=\frac{o p p}{h y p}$

where $\theta=50^{\circ}$ , opp = BC and hyp = AB

Thus, substituting these in the formula, we get,

$\sin 50=\frac{B C}{A B}$

From the diagram, the value of AB is 3.

Substituting the value and simplifying the expression, we have,

$0.7660=\frac{B C}{3}$

Multiplying both sides by 3, we get,

2.298={B C}

Rounding the answer to the nearest hundredth, we have,

BC=2.30

Thus, the length of BC is 2.30
