Answer:
Step-by-step explanation:
We are given that:
Where θ is in QIV.
And we want to find the value of tan(θ).
Recall that cosine is the ratio of the adjacent side over the hypotenuse.
Therefore, the opposite side is:
Next, in QIV, only cosine is positive: sine and tangent are both negative.
Tangent is the ratio of the opposite side to the adjacent. So:
Substitute. Tangent is negative in QIV. Hence:
Answer: C (154 m2)
Step-by-step explanation:
√19 = 4.36
√77 = 8.77
So integers between √19 and √77 are 5, 6, 7 and 8. And their sum is
5 + 6 + 7 +8 = <u>26</u>
