The angle 0 lies in quadrant ii .
cos 0 =

what is tan 0 ?

Step-by-step explanation:

Since we are in quadrant 2, sine is positive.  Since sine is positive and cosine is negative, then tangent is negative.

Now I'm going to find the sine value of this angle given using one of the Pythagorean Identities, namely .

If given , then we have by substitution of .

Let's solve:

for .

Subtract 4/9 on both sides:

Simplify:

Square root both sides:

===========

Multiplying top and bottom by 3 gives:

I'm going to move the factor of -1 to the top:

answer: this is not a question

step-by-step explanation: this is a answer

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
