Answer:
B) 6.68
Step-by-step explanation:
Use Cosine.
Cosine= Adjacent ÷ Hypotenuse
In this case the base you want to find is adjacent to the angle, 42°. Hence,
Cos (42)= adjacent ÷ hypotenuse
Cos (42) = x ÷ 9
x = Cos (42) × 9. Input that into your calculator.
x= 6.68
To remember the trigonometric ratios/formulas
Use the acronym, SOHCAHTOA
Hope this helps!!!!
4/5= 0.8
12 4/5= 12.8
Number in ones place: 2
Number in tenths place: 8
Since 8>5, the number rounds up.
Final answer: 13
Answer:
8, 14
Step-by-step explanation:
Any term in a Fibonacci sequence is found as
=
+ 
Thus
a₃ = a₁ + a₂ = 2 + 6 = 8
a₄ = a₂ + a₃ = 6 + 8 = 14
The next 2 terms are 8, 14
19.98. you can round it off to 20 if needed. It would be logical to round it.
