Answer:scales percent error=3.51%
Step-by-step explanation:
P ercent error = Experimental value - Theoretical value /Theoretical value x 100
Theoretical value = 6255 grams
Experimental value ( use of scale ) = 6475grams
Percent error =(6475- 6255)grams / 6255grams x 100
=220/6255 x 100
=3.51%

Answer:
A=51
a=22.2
c=28.6
Step-by-step explanation:
∠A=180-90-39
=51
a/sin51=18/sin39
a=22.2
c/sin90=18/sin39
c=28.6
