PLEASE HELP Which of the following would be a line of reflection that would map ABCD onto itself?
Square ABCD with B at 1 comma 3, A at 1 comma 1, D at negative 1 comma 1, and C at negative 1 comma 3.
A) x = 1
B) −x + y = 2
C) x − y = 2
D) 2x + y = 3

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
