Answer the given question and show workings. Question :
Given that θ = 3/5 , Cos alpha = 3/5 , where θ and alpha are acute. Find Sin ( θ+alpha).

Note : I'm writing alpha in words cuz I don't know how to type in the symbol.​

alpha=cos^-1(0.6)

alpha=53°

sin(37+53)

=1

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)

51-50
