Square PQRS has vertices at P(-2, 4), Q(-2, -1), R(3,-1), and S(3,4). What is the length of side PS?
Strike441 [17]

Answer:

The length of side PS is just the distance from point P to point S.

Point P (-2, 4)

Point S (3, 4)

So the length is the distance from -2 to 3, since the y coordinate is the same for both. The distance from -2 to 3 is 5 units.

So, PS is 5 units long.

Let me know if this helps!

Hallar el valor del cateto a
love history [14]

Answer:

a = 5.07

Step-by-step explanation:

Here, we want to get the value of the side marked a

What we have is a right triangle

so, to find the value of a, we are to use the correct trigonometric ratio

The angle given faces a, which makes a the opposite

the side measure faces the right angle and that makes it the hypotenuse

The trigonometric ratio that connects the two is the sine

The sine is the ratio of the opposite to the hypotenuse

mathematically;

sine 25 = a/12

a = 12 * sine 25

a = 5.07

Smush Parker and Kobe Bryant are having a three-point shooting competition. For each shot made, the player earns three points. F
Alina [70]

Answer: Kobe made 25 shots.


Step-by-step explanation:

let 'x' be the number of shot made and 'y' be the number of shots missed.

Then according to the question, we have the following equation:-

3x-5y=0\\\Rightarrow\ x=\frac{5y}{3}.......(1)\\\\x+y=40..............(2)

Substitute the value of x from (1) in (2), we get

\frac{5y}{3}+y=40\\\Rightarrow\frac{5y+3y}{3}=40\\\Rightarrow\frac{8y}{3}=40\\\Rightarrow\ y=\frac{40\times3}{8}\\\Rightarrow\ y=15

From(1), x=25

Hence, Kobe made 25 shots.
