Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of si

aliya0001 [1]

Answer:

Trigonometric ratios

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse (the side opposite the right angle)

To find sin x and cos y, we must first find the length of the hypotenuse (PO) of the given right triangle.

To do this, use Pythagoras' Theorem:

$a^2+b^2=c^2 \quad \textsf{(where a and b are the legs, and c is the hypotenuse)}$

Given:

a = 6
b = 8
c = PO

$\implies 6^2+8^2=PO^2$

$\implies PO^2=100$

$\implies PO=\sqrt{100}$

$\implies PO=10$

Using the found value of the hypotenuse and the trig ratios quoted above:

$\implies \sf \sin(x)=\dfrac{6}{10}=\dfrac{3}{5}$

$\implies \sf \cos(y)=\dfrac{6}{10}=\dfrac{3}{5}$

Therefore, $\sf \sin(x)=\cos(y)$

Twice the sum of 13 and x is not greater than 15

Kobotan [32]

Answer:

x = 0

Step-by-step explanation:

This is saying that 2(13x) < 15

If you have 2[13(0)] < 15

It will come to 2(0) < 15

This equals 0 < 15 which is true therefore making the x value = 0
