(1 point) List all angles in radians that satisfy the equation 2cos(x)sin(x)−2‾√cos(x)=0. Each item in the list should be an expression of the form θ+kω where 0≤θ<2π, and ω is the smallest positive period of the function f(x)=2cos(x)sin(x)−2‾√cos(x), and k=⋯,−2,−1,0,1,2,⋯ ranges over the integers. Separate items by commas. Note: You are not allowed to use decimals in your answers.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
