Answer:

cos x

Step-by-step explanation:

r/q represents the sine of angle y: opposite side / hypotenuse.

In terms of x, r / q is the ratio adjacent side / hypotenuse, which is cos x.

Answer:

The correct answer is option C. Cos x

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

From the figure we can see that, a right triangle with angles and sides are given.

To check the options

1) Sin x = Opposite side/Hypotenuse = p/q

2). Cos y = Adjacent side/Hypotenuse =p/q

3). cos x= Adjacent side/Hypotenuse = r/q

4). tan y = Opposite side/Adjacent side = r/p

Therefore the correct answer is option C. Cos x

Sharonda is plotting quadrilateral PQRS on the graph below. She will plot the fourth and

lana [24]

Answer:

11 units

Step-by-step explanation:

Length of side PS can be calculated using the distance formula, $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Where,

$P(-2, 5) = (x_1, y_1)$ (the coordinate of P is gotten from the graph)

$S(9, 5) = (x_2, y_2)$ (given)

$PS = \sqrt{(9 - (-2))^2 + (5 - 5)^2}$

$PS = \sqrt{(11)^2 + (0)^2}$

$PS = \sqrt{121} = 11 units$

Which one of the following would prove that two triangles are congruenta

White raven [17]

Answer:

Corroponding side lengths are equal

Step-by-step explanation:

Two triangles may have the same areas, but the sides might be different or in different spots than each other. The same goes for perimeter, therefore it doesn't mean that they are congruent. If two triangles had the same angle measures, it could still have any size side lengths. When corrosponding side lengths are equal, they have the same angles as well, so they are only congruent in this example.

Hope this helps :)
