Ответ:
DF=9.28 units
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The sine of angle of 55 degrees is equal to divide the opposite side to the angle of 55 degrees by the hypotenuse
so
sin(55°)=EF/DF
where
EF is the side opposite to the amgle of 55 degrees
DF is the hypotenuse
we have
EF=7.6 units
substitute
sin(55°)=7.6/DF
DF=7.6/sin(55°)
DF=9.28 units
