Question

Need some help please​

Answer 1

see explanation

Explanation:

sinR =
`(TS)/(TR)` =
`(60)/(68)` =
`(15)/(17)`

cosR =
`(RS)/(TR)` =
`(32)/(68)` =
`(8)/(17)`

tanR =
`(TR)/(RS)` =
`(60)/(32)` =
`(15)/(8)`

Answer 2

Sin(R) = 15/17

Cos(R) = 8/17

Tan(R) = 15/8

Explanation:

Sin = Opp./Hypo, Cos = Adj./Hypo. and Tan = Opp./Adj.

So

Sin(R) = Opp./Hypo = 60/68 = 15/17

Cos(R) = Adj./Hypo =32/68 = 8/17

Tan(R) = Opp./Adj. = 60/32 = 15/8
