Answer:
hey! You have to use the trigonometric formula because it's a rectangle triangle:
(a^2)+(b^2)=(c^2)
(11^2)+(11^2)=(c^2)
√(242)=√(c^2)
15.56=c
So basically, the answer is D!
Answer:
i think it’s B
Step-by-step explanation:
Sine the last number (3) is less than 5 it is rounded to 257.67
Assuming n starts at 0, the fourth term would be n=3. c(3)=-7+6(2)=12-7=5
6 is easy
7. never divide by a fraction, flip ot upside down and multiply, so multiply by 5 on both sides
8. subtract 3.45 on both sides
9. the answer is just 1
