Answer:
Step-by-step explanation:
tanR = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{PQ}{QR}[/tex]
= [tex]\frac{10}{24}[/tex]
= [tex]\frac{5}{12}[/tex]
sinR = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{PQ}{PR}[/tex]
= [tex]\frac{10}{26}[/tex]
= [tex]\frac{5}{13}[/tex]
cosR = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{QR}{PR}[/tex]
= [tex]\frac{24}{26}[/tex]
= [tex]\frac{12}{13}[/tex]
