Review the proof (not in order) of the identity tan(theta/2)=plus or minus square root (1-cos(theta))/(1+cos(theta)). What is the correct sequence of steps? A. 1-3-2-4-5
B. 1-3-4-2-5
C. 1-4-2-3-5
D. 1-4-3-2-5

step-by-step explanation:

this is not a question

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

at least two

step-by-step explanation:

it has to have an angle of 90 degrees
