Answer:
the unknown side of triangle is 15 in :)
Answer:
C ni, because 17 isn't divisible by 7 it 3
Answer:
B
Step-by-step explanation:
(Sorry about the crude drawing)
The drawing shows what the triangle with a terminal side in Quadrant IV looks like.
Secant is the ratio of the hypotenuse to the adjacent side of the angle. In the given ratio, we can set 5 as the hypotenuse and 2 as the adjacent side (you can see them labeled in the picture).
Now, we want to find sin, which is (opposite)/(hypotenuse). However, we don't know the opposite. We can find it by using the Pythagorean Theorem:
![\sqrt{5^2-2^2} =\sqrt{25-4} =\sqrt{21}](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2-2%5E2%7D%20%3D%5Csqrt%7B25-4%7D%20%3D%5Csqrt%7B21%7D)
So, the opposite side is
. But, we see that since it's in the fourth quadrant, it must be negative, so we have opposite =
. Now, we can find the ratio because hypotenuse = 5:
sin(θ) =
.
Thus, the answer is B.
Hope this helps!
Answer is D. F(x) = -1/4x
Answer:
Using Pythagorean theorem:
x = sqrt( 15^2 + 36^2) = 39
