Ok, so the |-9| = 9. |-2|=2.

The cup (buried at -9 feet) is farther from the surface because 9 > 2/

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

What are the measures of ∠1, ∠2, and ∠3? Enter your answers in the boxes.

GarryVolchara [31]

Answer: m<1 is 60, m<2 is 60, and m<3 is 120

Step-by-step explanation:

M<1 is 60 and m<2 is also 60 because the interior triangle angles have to equal 180 so M<1 + m<2 + 60 = 180 so m<1 and m<2 are both sixty.

m<3 is 120 because m<2 and m<3 are supplementary so if a supplementary angle is equal to 180 then m<2 + m<3 = 180 and m<2 is 60 so m<3 is 120.
