Answer:
4.8 (you can check but that's what I got)
Step-by-step explanation:
First find the missing angle by subtracting the sum of the two given from 180°
[tex]180-(47+90) =[/tex]43°
Then use the Law of Sines to find the missing side
x/sinC = a/sinA
x/sin(90°)/3.5/sin(47°)
x=sin(90°)×(3.5/sin(47°))
x=4.7856...
x ≈ 4.8
