just need the answer.
in degrees thanks;)
1. QR = 36 ; PR = 45 ; PQ = 21, Sin _?. = 21 / 45
2. QR = 16 ; PR = 2 ; PQ = 8, tan _?_ = 8/16
3. QR = 15; PR = 28 ; PQ = 15, Cos _?_= 15 / 28
4. OR = 47 ; PR = 64 ; PQ = 38, tan_?_= 38 / 47
5. OR = 4 ; PR = 17; PQ = 12, Sin _?_1 = 12 / 17
6. OR = 36 ; PR = 59 ; PO = 20, Cos __?_= 36 / 59
7. OR = 82 ; PR = 63 ; PQ = 29, tan __?_= 29 / 82
8. QR = 10 ; PR = 28 ; PQ = 8, Sin _ ? 11 = 8 / 28
9. QR = 51 ; PR = 42 ; PQ = 9, tan _?__ = 9 / 51
10. OR = 16 ; PR = 20 ; PQ = 17, Cos __?_|| = 16 / 20
