Tanx sinx (cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x cscx- sinx)
=(sinx/cosx)((cos^2x 1/sinx- sinx)
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(sinx/cosx)((cos^²x - sin²x)] / sinx
=(1/cosx)((cos^²x - sin²x)]
=(1/cosx)(2cos²x====> = 2 cos x]
Answer:
I'm sorry but I can't answer your question because there's no details
Step-by-step explanation:
The <em><u>correct answers</u></em> are:
4 lines of symmetry, and yes, 90 degree rotational symmetry.
Explanation:
Lines of symmetry are lines through which a figure an be folded and be the same on each side of the fold. This figure can be folded in half horizontally, vertically, and through both diagonal; this is 4 lines.
Rotational symmetry means you can turn a figure and have it look the same. This figure can be rotated multiples of 90 degrees and look the same.
The value of x that makes the equation true would be -190.
x = -190
