The solution to the system is (-2,-8)
Answer:
Step-by-step explanation:
Given:

To Prove:
AB║DE
Solution:
Since, corresponding sides of ΔACB and ΔDCE are proportional,

Both the triangles will be similar.
ΔACB ~ ΔDCE [By SAS property of similarity]
Therefore, ∠1 ≅ 2 [CPCTC]
Since, ∠1 and ∠2 are the corresponding angles
Therefore, AB║DE [Converse of corresponding angles theorem]
Ummm ....... I think x=80
Angela uses this recipe, but she using twelve times the amount of everything. Therefore, we will do (150g*12=1,800). To turn this to kg, we will divide by 1,000 to get 1.8 kg.
hope this helped!
