Ответ:
1.64 units
Step-by-step explanation:
step 1
Find the measure of AB
In the right triangle ABC
sin(x)=AC/AB
AB=AC/sin(x)
substitute the given values
AB=4/sin(39°)=6.36 units
step 2
Find the measure of AD
In the right triangle ADC
sin(y)=AC/AD
AD=AC/sin(y)
substitute the given values
AD=4/sin(58°)=4.72 units
step 3
Find the difference in length between segments AB and AD
AB-AD=6.36-4.72=1.64 units
