Answer:
m<S=66.5
Step-by-step explanation:
The sum of the angles = 360
(6x-6)+(4x-10)+(5x-11)+(5x+13)+(4x+2) = 360
24x-12=360
24x=372
x=15.5
S=5x-11 = 5*15.5-11=66.5

Answer:
Think
Step-by-step explanation:
Think its 2.
Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5
