Use the given diagram to find the length of the unknown leg rr. Leave answer in simplified radical form. NO Decimals!

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)

i dont get the question

step-by-step explanation:

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
