Can someone help me with this question.

Explanation:

angle BCA ≅ angle ECD . . . . . . vertical angles are congruent

∆BCA ≅ ∆ECD . . . . . . . . . . . . . . SAS congruence theorem

BA ≅ ED . . . . . . . . . . . . . . . . . . . .CPCTC

Based on the given congruences and the congruence of the vertical angles at C, we can invoke SAS congruence to show ∆BCA ≅ ∆ECD. Then the desired segments are congruent because corresponding parts of congruent triangles are congruent.

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
