If
find
the value
sino - cose then
a tano & cose o.​

Step-by-step explanation:

tan(x y) = (tan x tan y) / (1 tan x tan y)

sin(2x) = 2 sin x cos x

cos(2x) = cos^2(x) - sin^2(x) = 2 cos^2(x) - 1 = 1 - 2 sin^2(x)

tan(2x) = 2 tan(x) / (1 - tan^2(x))

sin^2(x) = 1/2 - 1/2 cos(2x)

cos^2(x) = 1/2 + 1/2 cos(2x)

sin x - sin y = 2 sin( (x - y)/2 ) cos( (x + y)/2 )

cos x - cos y = -2 sin( (x - y)/2 ) sin( (x + y)/2 )

a/sin(A) = b/sin(B) = c/sin(C) (Law of Sines)

(a - b)/(a + b) = tan [(A-B)/2] / tan [(A+B)/2] (Law of Tangents)

answer:

2 over 5 is the correct option which lets grace find the x-coordinate for point c.

step-by-step explanation:

to find: the fraction to find the x-coordinate for point c.

given the endpoints are a = (3,2) b = (6,11)

ratio is given as ac: bc = 2: 3

total number of units for the entire line ab = sum of ratio = 2+3 = 5.

to obtain c, taking ac, we get  

x coordinate of c = value taken from the ratio / sum of ratio =   2/5.

hence, the correct option is 2 over 5.
