Which of these is a correct step in constructing congruent angles? Use a straightedge and draw an arc across the first arc from a leg of the given angle.
Use a straightedge to measure the width between the points where the first arc cuts both legs of the given angle.
Use a compass and draw an arc across both the legs of the given angle.
Use a compass and join points to make the new leg of the congruent angle.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.

the answer is  

c.

14,469 cubic feet

i know this one is right
