the solution is the point
step-by-step explanation:
we have
> equation a
> equation b
adds equation a and equation b

the first option is the answer.
sas (side angle side)
aa(angle angle)
sss(side side side)
sas you have to find two sides with an angle in between
aa you find two angles because it will always add up to 180
sss find all sides
