By looking at ur answer choices, I am assuming the width is 2/5 inches and the length is 3/5 inches.
A = L * W
A = 3/5 * 2/5
A = 6/25 in^2 <==
Answer:
14, 12
Step-by-step explanation:
the first is right I think
r+p=28 can also be written as 28-p=r
so 28-14=14
and 28-16=12
hopefully that works
Answer: I don’t get the question but I think this is the answers.
If the value of cos(θ) is negative, this angle (θ) can only be in one of two quadrants; the sine quadrant or the tan quadrant. In the sine quadrant, tan(θ) must be negative, but since tan(θ) > 0, we can safely say that the angle (<span>θ) is based in the tan quadrant.
We know that cos(</span><span>θ) = - Adjacent / Hypotenuse, and in this case Adjacent = 2 and Hypotenuse = 5. Using Pythagoras' theorem, we can find the opposite side of the right angled triangle situated in the tan quadrant...
</span>Adjacent² + Opposite² = Hypotenuse²
Therefore:
2² + Opposite² = 5²
Opposite² = 5² - 2²
Opposite² = 21
Opposite = √(21)
------------
Now, sin(θ) must be negative, as the right angled triangle is in the tan quadrant. We also know that sin(<span>θ) = Opposite / Hypotenuse, therefore:
sin(</span><span>θ) = - [</span>√(21)]/[5]
