Answer:
I guess it is the Answer C
Because all 3 sides are given for both triangles you can use the SSS theorem
The first decimal point is tenth. 4.88
when rounding, we just look at the number right after the number you want to round to. it's 8 right? since 8 is closer to 10 than 0,
we round it to 4.9
(4.8 + 0.10)
3(2y-3)=27
6y-9=27
6y=36
y=6
