Answer:
sec Θ =
Step-by-step explanation:
Using the trigonometric identity
sec²Θ = tan²Θ + 1
Since 270° < Θ < 360° ← that is fourth quadrant, then
sec Θ > 0, thus
sec²Θ = (- )² + 1 =
+ 1 =
, then
sec Θ = =
The IUCN Red List of Threatened Species notes that 36% of the 47,677 species assessed are threatened with extinction. How many s
1 answer:
Answer:
17,164 species.
Step-by-step explanation:
We have been given that the IUCN Red List of threatened Species notes that 36% of the 47,677 species assessed are threatened with extinction.
To find the number of species that are threatened with extinction we will find 36% of 47,677.
Therefore, 171164 species are currently threatened with extinction.

Check the picture below.
keeping in mind that the point of tangency for a radius line and a tangent is alway a right-angle, since the "red" chord is parallel to the "green" tangent line outside, then the chord is cutting the "green" radius there in two equal halves at a right-angle, as you see in the picture.
we know the chord is 10 units long, so 5 + 5, since is perpendicularity with the radius will also cut the chord in two equal halves.
anyhow, all that said, we end up with triangle you see on the right-hand-side, and then we can just use the pythagorean theorem.
