Answer:
x = 2* pi* n
Step-by-step explanation:
cos(2x) cos(x) + sin(2x) sin x =1
We know cos(s) cos(t) + sin(s) sin(t) = cos(s - t)
Using s =2x and t = x
cos (2x-x) =1
cos (x) =1
We know this occurs at 0, 2pi, 4 pi etc
x = 2* pi* n where n is an integer
Answer:
5/6 = v + 2/7
Step-by-step explanation:
5/6 = v + 2/7
23/42 - v = 0
5/6 = 1/7 (7 v + 2)
HL Theorem would prove these two triangles are congruent.
The answer is 523 because 4,707 divide 9 to be equal numbers for each one I hope it helps
