The diagram below shows a flat mirror reflecting light
in the above image, what is represented by line D?
A .the mirror
B . the angle of reflected light
C . the angle at which light hits the surface of the mirror
D .the imaginary line used to measure angies of rays

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

ammonium chloride & tallow

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
