Pls help me with this

problem 1) for a it would be up 2 and right 2. for b it would be down 2 and right 2.

problem 2) for a it would be down 2 left 2 and for b it would be down 2 and up right 2

explanation -step by-step explanation:

An image which is like a reflection in a mirror. Everything is the same, except reversed. Here the left and right sides of this lovely dog are mirror images of each other.

Step-by-step explanation:

a)

clearly, A and B are mirrored images of each other around the x-axis.

and the equation of the x-axis is simply

y = 0

b)

this is trickier.

first of all, the mirror line is now vertical and not horizontal.

and where is it ? of course, in the middle between A and B.

how many units are there between A and B ?

I am counting 5. so, the middle between them is 2.5 units.

so, let's go e.g. from A 2.5 units to the right (in the direction of B).

where do we end up ? at x = 0.5

and that is also the equation of the vertical line there.

again

x = 0.5

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
