The measure of angle fjg = pi over 6 and the measure of fk is pi over 8. what is the measure of ghk

the answer is 1/4

step-by-step explanation:

the correct answer would be the third option

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
