Answer:
sin is only positive in 1st and 2nd quadrants
Step-by-step explanation:
As you may know, sine is defined as y-term or value in (x, y). You can go see a unit circle.
Remember that sine is y while cosine is x.
Since sine is y, It'd be a horizontal line. And since it's a horizontal line, it intersects two points in a unit circle.
Q1 and Q2 both are positive while Q3 and Q4 are negative.
C. Acute vertically opposite angles
I believe the answer its the 3rd one NOT SURE
If it were always finding the opposite of the number, then
we would have to say that the absolute value of 7 is -7 .
We know that's not true.
It's better to tell Angelique that finding the absolute value
of a number means just looking at the size of the number
and ignoring its sign completely.
1.) the relationship between y and 76 is that they are congruent; perpendicular to each other. They equal the same
y= 76
not sure abt the other one
