The slope is - 1/4.
Moving the x to the right side of the equation and then dividing by - 16 the result is - 1/4
28. One way to do this is to split it up into 10 congruent isosceles triangles whose vertices meet at the center of the decagon.
The vertex angle will be 36 degrees and base will be 4 cm.
Work out the height of one of these triangles:-
tan 18 = 2 / h
h = 2 / tan 18 = 6.155 cm
So the area of this triangle = 1/2 * 4 * 6.155 = 12.311 cm^2
So area of the decagon = 10 * 12.311 = 123.1 cm^2 to nearest tenth.
Its the 3rd choice.
