Which postulate or theorem proves △abc≅△edc ? sas congruence postulate asa congruence postulate sss congruence postulate hl congruence theorem .

SAS Congruence Postulate

Step-by-step explanation:

In ΔABC and ΔDCE

AC=CE [given]→Side

∠ACB=∠DCE [vertically opposite angles]→Angle

BC=DC [given]→Side

∴ ΔABC ≅ ΔDCE [SAS congruence postulate]

if x decreases by 4 then y increases by 10

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
