Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

A

Step-by-step explanation:

Triangle ABC has vertices A(1,1), B(5,1) and C(3,4).

Reflectio across the x-axis has the rule:

(x,y)→(x,-y),

so

Rptation by 180° has the rule

(x,y)→(-x,-y),

so

These points A'', B'', C'' differ from original vertices, so the image triangle is not the same as the pre-image triangle.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
