Question

Select all of the following that are true. *

sinA=18/30
sinA=3/5
cosA=10/6
cosA=8/10
cosA=5/3
tanF=24/18
tanF=3/4
tanD=3/4
sinD=18/30

Answer 1

Explanation:

sin A =
`(BC)/(AC)` =
`(6)/(10)` =
`(3)/(5)`

cos A =
`(AB)/(AC)` =
`(8)/(10)` =
`(4)/(5)`

tan F =
`(DE)/(FE)` =
`(24)/(18)` =
`(4)/(3)`

tan D =
`(FE)/(DE)` =
`(18)/(24)` =
`(3)/(4)`

sin D =
`(FE)/(FD)` =
`(18)/(30)` =
`(3)/(5)`
