fasai is x years old. Fasai has a brother called orma. the sum of the two boys age is 20 years. express the sum of their ages in form of y=a(x-b)²+ c and how old must fasai be to make the product of their age a maximum?

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)

answer: 0.64

step-by-step explanation:

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.
