Answer:
option D
Step-by-step explanation:
Given in the question, a right angle triangle FGH.
Base of triangle = 12
Height of triangle = 5
Hypotenuse of triangle = 13
To solve the question we will use trigonometry identity.
cos(F) = adj / hypo
cos(F) = height / hypo
cos(F) = 5 / 13
So the cosine ration for angle F is 5 / 13
