The statement that is true about the factorization of 30x2 + 40xy + 50y2 is that <span>The factorization of the polynomial is 10(3x2 + 4xy + 5y2).</span>
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Final answer: D
