Answer:

C

Step-by-step explanation:

using the cosine ratio to find p

cos 45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{p}[/tex]

cross- multiplying gives

p × cos45° = 6 → [ cos 45° = [tex]\frac{1}{\sqrt{2} }[/tex]]

p × [tex]\frac{1}{\sqrt{2} }[/tex] = 6

multiply both sides by [tex]\sqrt{2}[/tex]

⇒ p = 6[tex]\sqrt{2}[/tex] ( third option on list )
