Presuming that I am reading the question correctly, the answer is D. A trigonometric table would provide all of the ratios of the sides in relationship to the angles. Sin, cos, and tan are just one example of the ratio.
Answer: the first one
Step-by-step explanation:
It is the only one that is right
angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)
Answer:
112
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
you can divide the second term by the first term to solve
39/-13 = -3
then, I like to check that this fits with the third term
39*-3 = -117
so the common ratio is -3
