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
