Which of the following statements is true?
a sin 30º = cos 30"
b. sin 35º = cos 55"
c. sin 60" = cos 60"
d sin 55° = cos 25°

d

Step-by-step explanation:

sin 55° = cos 25°

because they complete each other to 90°

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
