Answer:
9.7%
Step-by-step explanation:
Given data
Expected value= 277
Actual value= 250
%Error= Actual- Expected/Expected *100
%Error= 250-277/277 *100
%Error= 27/277 *100
%Error= 0.097*100
%Error= 9.7
Hence the error is 9.7%
To find the number of chaperones, you could find the total number of students that are going on the field trip and then break this number into groups of 8.
(158 + 139)/8
297/8 = 37.125
You will need a minimum of 38 chaperones for the 297 students. If there is any remainder(decimal) you will need an extra chaperone so the groups do not exceed 8.

We can solve this problem by applying trigonometric ratios.
sin27=DC/BD
BD=DC/sin27
=8.8
