Question

Help me solve these questions please.

Answer 1

see explanation

Explanation:

cos C =
`(adjacent)/(hypotenuse)` =
`(BC)/(AC)` =
`(24)/(51)` =
`(8)/(17)`

-----------------------------------------------------

tan Z =
`(opposite)/(adjacent)` =
`(XY)/(ZY)` =
`(15)/(20)` =
`(3)/(4)`

---------------------------------------------------

sin C =
`(opposite)/(hypotenuse)` =
`(AB)/(AC)` =
`(60)/(65)` =
`(12)/(13)`
