The sum of two consecutive numbers is 157. This equation, where n is the first number, represents the situation: 2n + 1 = 157.

78

Step-by-step explanation:

subtract 157 by the one and divide 156 by the 2 or two consecutive numbers

to get 78

D. ∠B≅∠E

Step-by-step explanation:

since the congruence of angle A and D and sides AB and DE  is given,

the only thing needed to prove that the triangles are congruent by ASA is angle B and E. This is because both triangles have congruent included sides between their angles.
