Use trigonometry
sin 42 = a / 21
a = 21 sin 42 = 14.05
Based on this question, one thing that we would seriously consider would be the fact of first, doing

first. By doing this, it would then give us our answer as 16. By us understanding this point of view, we would then consider that this would then be your answer. That would then include that there would then be 16 pairs of the "enantiomeric pairs", and that would then be the possible estimate.

The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10) = -1
slope is -1.
They are on quarenent one
Answer:
No, similar figures need to have corresponding sides proportional and corresponding angles congruent.
