The image point of A after a translation right 5 units and up 5 units is the point B(13,9). Determine the coordinates of the pre-image point A.

A(8,4)

Step-by-step explanation:

Lets assume A(x,y)

then B(13,9)

X+5=13

x=13-5

x=8

again Y+5=9

Y=9-5

Y=4

so A(8,4)

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)
