Answer:
20%
Step-by-step explanation: The percent of error formula is |(theoretical value-actual value)/actual value|=percent of error. Substitute the values in. |(2.8-3.5)/3.5|=|(-0.7)/3.5|=0.2. The percent equal to 0.2 is 20%.
Here we have a 90 degrees triangle where we can use trigonometric functions.
Here we can use tan(x) function because it requires legs of triangle that are given and inverse function of tan(x) will than give us asked angle
tan(x) = 7.4/9.3 = 0.7956
x = arctan(0.7956) = 38.505 ≈ 39 degrees.
