A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. so for example, 21 is A prime number. no two whole numbers times themselves would equal 21. To figure out if a number is prime, divide it by 2. If you don't get a whole number, it is prime
With a triangle that you already know two angles, you can find the third one fairly easily by adding the two you already have, and then subtracting that sum from 180. Now that you have the third angle measure, you know that you have an isosceles triangle, because two of the angle measures are 45. Then, you know that two sides of the triangle are equal (both legs). Since they are equal, you know that those two legs squared added up equal 3 sqrt2 squared, or 18. Now you have to solve this equation, x squared + x squared = 18, or when you simplify, x = 3. That's the answer!
Answer:
Median: 20
First quartile: 13
Third quartile: 59
Minimum: 12
Maximum: 83
Step-by-step explanation:
Answer: The correct option is option third .
Explanation:
The given equation are,
In the second equation the like terms are aligned, therefore, we have to aligened only first equation.
The first equation is,
Subtract 0.8 from both the sides.
Add 0.4y on both the sides.
So, after aligned the system of equation have two equations.
Both equation are show in third option, So third option is correct.
1) Use the pathagreom theorem; a^2+b^2=c^2
(The hypotenuse is always c. The other two legs can be either a or b.)
*use x for the unknown side*
1. Plug in the measurements
4^2+x^2=8.5^2
2. Solve
16+x^2=72.25
RADICAL(56.25)=> 7.5
The measure of the other side of the triangle (x) is= 7.5 m
2) Draw a square with the measure of 20 cm on each side.
Draw a diagonal line across the square.
(Use the pathagroeam theorem)
We know that the legs are 20, and 20. The hypotenuse is what we are trying to find (x).
1. Plug in the measurements
20^2+20^2=x^2
2. Solve
800= x^2
20 RADICAL(2)=> 28.28
The measure of the other side of the triangle (x) is= 28.3 cm
