Complementary means the two angles add up to 90 degrees. Do 90 - 79 to find the other angle.
It's 11 degrees.
17.24
Since 7 comes after 5 we need to round to the next number.....18.00
17.24 rounded to ones = 18.00
Hope I helped:P
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%
15X=12X+12
Subtract 12X
3X=12
X=4
