WebUnfortunately the mistake lies in the very first step.... Sal constructs CF parallel to AB not equal to AB. We know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal).

WebThe first thing to notice is that this triangle has different labels: PQR instead of ABC. But that's OK. We just use P,Q and R instead of A, B and C in The Law of Sines. Start with: sin R / r = sin Q / q Put in the values we know: sin R / 41 = sin (39°)/28 Multiply both sides by 41: sin R = (sin (39°)/28) × 41 Calculate: sin R = 0.9215...
