Select the correct answer from each drop-down menu. In the figure, , and both lines are intersected by transversal t. Complete the statements to prove that ∠2 and ∠8 are supplementary angles. (given) m∠2 = m∠7 ( ) m∠7 + m∠8 = 180° ( ) m∠2 + m∠8 = 180° (Substitution Property) ∠2 and ∠8 are supplementary (definition of supplementary angles)

depending on others is critical to survival. my source is apex!

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
