Looking for any help ​

Answer 1

Explanation:

Hypotenuse is the side opposite to 90°.

`Sin \ R = (opposite \ side \ of \ angle \ R)/(Hypotenuse)\\\\`

`= (PQ)/(PR)\\\\\=(36)/(60.40)`

`Cos \ P =(adjacent \ side \ to \ angle \ P)/(hypotenuse)\\`

`=(PQ)/(PR)\\\\\\=(36)/(60.40)`

`Tan \ R =(opposite \ side \ to \ angle \ R)/(adjacent \ side \ to \ angle R)\\\\`

`=(PQ)/(QR)\\\\\\=(36)/(48.50)`

`Cot \ R = (adjacent \ side \ of \ angle \ R)/(opposite \ side \ of \ angle \ R)`

`=(QR)/(PQ)\\\\\\=(48.50)/(36)`
