Answer:
A
Step-by-step explanation:
A rhombus is a quadrilateral whose four sides all have the same length. if you look at the picture I sent, <u>A</u>(6,-1) forms a rhombus where all of the sides are an equal length.
I believe since ABD is 60, DBC is also 60 and then ABC is 120
315+210 =525 525+210=735 735+210=945
after 7 hours of work they have earn 945
any question ?
