You can divide the larger number by the smaller number for all of them and see if they all match. If they dont then its not porportional.
Hello There!
The third missing length would be 68°
All sides of a triangle always add up to 180°
We take the two sides we do know, add them together and then subtract the two sides added together from 180°
Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units
