triangle d e f is shown. angle e f d is a right angle. the length of e f is 24 and the length of d f is 7.
which trigonometric ratios are correct for triangle def? select three options.
sin(d) = startfraction 24 over 25 endfraction
cos(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 24 over 7 endfraction
sin(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 7 over 24 endfraction
