The complement to 25 degrees would be 65 because 25 + 65 = 90. Complementary angles are always equal to 90 degrees, no more, no less.
Dependent variable
This X2/X = X ==========yes X/3 = ?????? ==============No Yes it can. However, dividing by a variable doesn't always work since the variable could evaluate to zero, and you cannot divide by zero. Similar is true if the non-variable is zero.
It is 90
Angle + Its Complement = 90 degrees Angle = Its Complement + 8 degrees2*(Its Complement) + 8 degrees = 90 degrees2*(Its Complement) = 82 degreesIts Complement = 41 degreesAngle + 41 degrees = 90 degreesAngle = 49 degrees
In Boolean algebra, the law of double complementation states that a variable is equal to its double complement. This means that applying the complement operation twice to a variable yields the original variable. This law is useful in simplifying Boolean expressions and can help in reducing the complexity of logic circuits.
the y variable always changes and x is constant
The variable in the experiment that is always the same
dependent variable always go on y.axis on the graph.
Always isolate the varible
no
constant variable
Yes. A variable by itself, or anything that contains a variable, would be a variable expression (unless the variable cancels out, as in "x - x", which always has the same value).
x is used a lot to represent an independent variable. When time is the independent variable t is often used as well.
It is very common to use, but it is not the only variable you can use.
Always changing
The independent variable is always on the x-axis of a coordinate plane. The dependent variable is always on the y-axis. This is true because y always depends on x.
