Answer:
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]
SAS congruence postulate tells that if two sides and the included angle of one triangle are congruent to two sides and the included angle of other triangle, then the two triangles are congruent.
This is SAS. Notice you have 2 sides that are equal to each other and the vertical angle between them. Since the angle is between the 2 sides then the postulate that works is SAS.
I don’t know it’s could be better if I didn’t have any money for that you could do it omg is it like that a lot but you don’t want it anyway I can do
Answer:
The number b is bigger than the number a by of a.
Step-by-step explanation:
1. If the number a is smaller than the number b by 1/5 of b, then
Thus,
2. Consider the expression
This gives you that the number b is bigger than the number a by of a.
The correct answer is (70,50) as it’s proportional to the line because it crosses the point (45,30)
