Please help! Doing online because of pandemic! For line b, d, and e, line d is parallel to line e, and m∠1 = 81°.
Part A: In complete sentences, explain the relationships between all pairs of special angles 1, 2, 3, and 4 created by transversal line b and parallel lines d and e.
Part B: For the given diagram, use the measure of the special angle relationships created by transversal line b and parallel lines d and e to find the measures of ∠2, ∠3, and ∠4.

ART A:  Angles 1 and 4 are Corresponding Angles.  Angles 1 and 3 are Vertical Angles.  Angles 1 and 2 are Adjacent Supplementary Angles.  Angles 2 and 3 are also Adjacent Supplementary Angles.  Angles 3 and 4 are Opposite Interior Angles.  

PART B:  

<2=99 °

<3=81 °

<4=99 °

1) is right

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
