Answer:MP, NP, MN
Step-by-step explanation:
How do you find the sides of a 30 60 90 triangle?.
A 30-60-90 triangle is a special type of right triangle that has angles of 30 degrees, 60 degrees, and 90 degrees. It has the following properties:
The side opposite the 30-degree angle is half the length of the hypotenuse (the side opposite the 90-degree angle).
The side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle.
To find the sides of a 30-60-90 triangle, you can use these properties.
If you know the length of the hypotenuse (the side opposite the 90-degree angle), you can find the length of the other two sides using the following formulas:
The side opposite the 30-degree angle: hypotenuse / 2
The side opposite the 60-degree angle: (√3) * (hypotenuse / 2)
If you know the length of one of the other two sides, you can use the above formulas to find the length of the hypotenuse and the other side.
For example, if you know the length of the side opposite the 30-degree angle, you can find the length of the hypotenuse by multiplying it by 2 and the length of the side opposite the 60-degree angle by multiplying it by √3
In summary:
The hypotenuse is always twice the length of the shorter leg.
The longer leg is √3 times the length of the shorter leg.
The hypotenuse is always the longest side in a 30-60-90 triangle.

What is the solution of the equation 2x y 5 and 3x 2y 4?.
Solving the 2 equations will give us the value of x to be -14 and that of y to be 33.
Here we have two equations
2x + y = 5 and 3x - 2y = 4
Now we will use the substitution method to solve the equations
The first equation is
2x + y = 5
or, y = 5 - 2x [1]
Let 3x - 2y = 4 be equation 2
Substituting the value obtained in equation [1] in [2] we get
3x - 2(5 - 2x) = 4
or, 3x - 10 + 4x = 4
or, x = -14 [3]
Substituting the value of x obtained in equation [3] to equation [1] we get
y = 5 - 2(-14)
or, y = 5 + 28

60% of tudent like wimming, 40% like dancing, 20% of tudent that like wimming like dancing , how many tudent don't like wimming
So, 40% of students don't like swimming.
We know that 60% of students like swimming, and 40% of students like dancing. We also know that 20% of students that like swimming also like dancing.
First, we can find the number of students that like swimming and dancing by multiplying the percentage of students that like swimming by the percentage of students that like dancing and also like swimming:
20% * 60% = 12%
This means that 12% of students like both swimming and dancing.
To find the percentage of students who don't like swimming, we can subtract the percentage of students who like swimming from 100%.
100-60 = 40%
So, 40% of students don't like swimming.

What was the intensity of the earthquake on the Richter scale?.
The intensity of the earthquake on the Richter scale of magnitude 5.3 can be calculated for moderate earthquakes, and a strong earthquake can be estimated at magnitude 6.3.
The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930s to measure the magnitude of earthquakes occurring in Southern California using relatively high frequency data from a nearby seismometer station. Developed. The magnitude of an earthquake is expressed on a scale called the Richter scale. The Richter scale is a base 10 logarithmic scale, meaning that each magnitude is ten times stronger than the last. So 2 is 10 times stronger than 1 and 3 is 100 times stronger. On the Richter scale, the increment is the amplitude of the wave. In the Richter scale, magnitude is represented by whole numbers and decimals. More destructive earthquakes are usually between magnitude 5.5 and 8.9. A truly destructive earthquake is an earthquake that exceeds magnitude 7 on the Richter scale.

B. How many player were old on that day?
a. On the 13th day the company sold the same number of each player.
b. 2,451 players were sold on that day.
a. The day on which the company sold the same number of players can be calculated by equating the values of y that we have ;
y = 191x-32 and y = -x² + 200x + 20
Equating both, we have;
191x-32 = -x² + 200x + 20
⇒x² -200x + 191x-20-32 = 0
⇒x²-9x-52 = 0
⇒x²-13x + 4x -52 = 0
⇒x(x-13)+4(x-13) = 0
⇒(x-13)(x+4) = 0
⇒x = 13 or -4
as days cannot be negative, so we choose only x = 13
This means that the company sold equal numbers of players on the 13th day.
