The Pythagorean theorem is the idea that the sum of the two legs which are both squared is equal to the hypotenuse's length squared.
*<em>look at the image I attached for a better explanation</em>
By looking at the picture, we are missing the leg's length, and by using the Pythagorean theorem, we get the equation
Thus the <u>missing side length is 12 cm</u>
Hope that helps!
Answer:
$14.16
Step-by-step explanation:
4.8 × 2.95. =14.16
You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2
Substitute the value of x to the first equation.
y = 2(-2) = 4
Nanometers are a really small measurement, one billionth of a meter, I believe.
So nanometers is used to describe tiny stuff, like atoms of a water molecule, and waves of light.
