Answer:

Here is a proof

Angle DEF = angle ABC

A transversal cutting two parallel lines makes alternate exterior angles equal

Sum of measures of angles 1 and 2 = 50° + 48° = 98° = measure of angle DEF = measure of angle ABC

But since s bisects angle ABC, then angle 4 = 98 / 2 = 49°

But angles 3 and 4 are vertical angles....therefore.... measure of angle 3 = 49°

Answer:

x⁴ + 3x³ + 4x² + 12x = 0

<=> x³(x + 3) + 4x(x + 3) = 0

<=> (x³ + 4x)(x + 3) = 0

<=> x(x² + 4)(x + 3) = 0
