To prove that △aed ~ △acb by sas, jose shows that . jose also has to state that ∠a is congruent to ∠? a. a b. d c. acb d. abcthe answer is a i couldn't find the answer anywhere else so here it is

match them up (i write them under each other so i can easily match up the sides and angles).

aed

acb

angles: a matches to a, e matches to c, and d matches to b

sides: ae matches to ac, ed matches to cb, and ad matches to ab.

answer: a) ∠a

47 - 90 = 43

43 - 180 = x

x = 137
