Question

angle EFD is 90 degrees because its a right angle I also just calculated that angle def is 30 degrees

Answer 1

It seems that angle EFD is a right angle because you mentioned it is 90 degrees. Additionally, you mentioned that you calculated angle DEF to be 30 degrees.

Answer 2

this means the measure of angle elf is

Answer 3

The measure of angle ELF would be 60 degrees because the sum of angles EFD and DEF (90 degrees + 30 degrees) equals 120 degrees, and the sum of the angles in a triangle is always 180 degrees. Therefore, angle ELF would be the remaining angle (180 degrees - 120 degrees).
