How do i find cos Z
maxonik [38]

Step-by-step explanation:

The cosine function, along with sine and tangent, is one of the three most common trigonometric functions. In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as 'cos'.

In any right angled triangle, for any angle:

The sine of the angle = the length of the opposite side

                                  the length of the hypotenuse

The cosine of the angle = the length of the adjacent side

                                     the length of the hypotenuse

The tangent of the angle = the length of the opposite side

                                     the length of the adjacent side

So in shorthand notation:

sin = o/h   cos = a/h   tan = o/a

An irrational number between -2 and -1<br><br> a rational number between -2 and -1
leva [86]

Answer:

An irrational number between -2 and -1 would be \frac{-\pi }{2}

A rational number between -2 and -1 would be -1.5

Step-by-step explanation:

\frac{-\pi }{2} = -1.570796... This number does not have repeating decimals, patterns, and it isn't a terminating decimal. It is irrational.

-1.5 is a terminating decimal, therefore it is rational, as well as between -2 and -1.

Use the quadratic formula to solve x^2-2x+2=0
Helen [10]
The quadratic formula is...
\frac{-b (+/-)\sqrt{b^2-4ac}}{2a}
your a will be in front of your x^2, b in front of your x, and c will be the number without an x. Plug those into the equation and you'll get two answers. That will be it
