Which of the following is not a solution to (3tan^2x-1)(3tan^2x-3=0 30˚ 120˚ 150˚ 225˚ 315˚

120°

It is convenient to evaluate the expression 3tan²(x) for each of the given angles and see which give 1 or 3 as a result. The result for 120° is 9, so that angle will not be a solution to this equation.

_____

Solutions will be angles that make the factors zero. The first factor is zero when ...

... tan²(x) = 1/3

... x = arctan(±√(1/3)) = ±30° + k·180° for some integer k

Here, the angles of interest are 30°, 150°.

The second factor is zero when ...

... tan²(x) = 1

... x = arctan(±1) = ±45° +k·180° for some integer k

Here, the angles of interest are 225°, 315°.

_____

its c or d   take a lucky guess my dude

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
