Answer:

Explanation:

1)


Sin \ \alpha = (oppsoite \ side \ of \alpha )/(hypotenuse)=(QR)/(PR)\\\\\\Cos \ \alpha = (adjacent \ side \ of \alpha )/(hypotenuse)=(PQ)/(PR)\\\\\\tan \ \alpha = (oppsoite \ side \ of \alpha )/(adjacent \ side \ of \alpha)=(QR)/(PQ)\\\\


Sin \ \beta =(opposite \ of\ \beta )/(hypotenuse)=(PQ)/(PR)\\\\\\Cos \ \beta =(adjacent \ of\ \beta )/(hypotenuse)=(QR)/(PR)\\\\\\tan \ \beta =(opposite \ of\ \beta )/(adjacent \ of\ \beta )=(PQ)/(QR)\\\\
