What are the correct trigonometric ratios that could be
used to determine the length of LN? Check all that apply.
sin(20°) = 8
cos(70°) =
tan(70) =
sin(20") = LŇ
COS(70) = 8

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
