Answer:
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)
y^2=169
y = √169
y = + / - 13
Answer
y = -13 or y = 13
