Answer:
-15
Step-by-step explanation:
The sum of the 2 numbers (-13) is a negative, meaning the missing number also has to be negative. To find it, you must ask yourself, what minus 2 would equal 13.
Answer:
The answer is A. $15.00
Step-by-step explanation:
Take 25% of 60 and that is 15. Please give me brainliest
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
