If sin(x) = squareroot 2 over 2 what is cos(x) and tan(x)
Bumek [7]

Answer:

cos(x) = square root 2 over 2; tan(x) = 1

Step-by-step explanation:

\frac{\sqrt{2} }{2}

was, before it was rationalized,

\frac{1}{\sqrt{2} }

Therefore,

sin(x)=\frac{1}{\sqrt{2} }

The side opposite the reference angle measures 1, the hypotenuse measures square root 2.  That makes the reference angle a 45 degree angle.  From there we can determine that the side adjacent to the reference angle also has a measure of 1.  Therefore,

cos(x)=\frac{1}{\sqrt{2} }=\frac{\sqrt{2} }{2} and

since tangent is side opposite (1) over side adjacent (1),

tan(x) = 1

Through: (3, -5) and (0, -2) <br><br><br>please add the steps please.​
Vlad [161]
1: -5 = 3m + c
2: -2 = 0 + c

From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m

-5 = 3m - 2
m = -1

The equation of line is y = -x - 2
