Answer:
By the definition of supplementary angles, angle 1 + angle 2 = 180° and angle 2 + angle 3 = 180°. Then angle 1 + angle 2 = angle 2 + angle 3 = 180°. Subtract angle 2 from each side. You get angle 1 = angle 3, or angle 1 ≅ angle 3.
Step-by-step explanation:
<u>The Complete/Correct Question Reads:</u>
By the definition of supplementary angles, angle 1 + angle 2 = _____ and angle 2 + angle 3 = ____ . Then angle 1 + angle 2 = angle 2 + angle 3 ______. Subtract angle 2 from each side. You get angle 1 = ______, or angle 1 ≅ ______.
-------------------------------------------------------------------------------------------------------------
By definition we know that if the Sum of Two Angles is Equal to 180° then the angles are Supplementary.
Now looking at the schematic we can see that <u>our Supplementary angle pairs</u> are:
So let us start solving.
∠1 ∠2
∠3 ∠2
Then, we have
∠1 ∠2 = ∠3 ∠2
<u>So subtracting </u><u>∠2 from each side we have</u>:
∠1 ∠2 ∠2 = ∠3 ∠2 ∠2
∠1 ∠3 OR ∠1 ≅ ∠3
<u>So your paragraph will be:</u>
its A :D.
AB = 8 and AD = 5
Ad=BC ( given in fig or as its is rectangle and sides of rectangle are equal )
so BC = 5

Divide the coefficient of the x term by 2, then square the result. This number will be added to both sides of the equation. For the quadratic equation x2+4x=96, the coefficient of the x term is 4.
