Find the remaining trigonometric functions of θ based on the given information.csc θ = 257 and cos θ < 0
katrin [286]
Cos(<span>θ) < 0, so we know it would be in Quadrant 2 or 3
then csc(</span>θ) = 257, but csc(θ) = \frac{1}{sin(θ)} = 257
==> sin(<span>θ) = \frac{1}{257}
it is positive, so now we can determine that is in Quadrant 2

sin(</span>θ) = opp./hyp both of opp and hyp are positive but adj suppose to negative because that way it leads the cos(<span>θ) < 0
</span>cos(<span>θ) = adj/hyp
</span>Pythereom to find the adj: 257^{2} -  1^{2}  = adj ==\ \textgreater \  adj  \sqrt{ 257^{2} -   1^{2} } ==\ \textgreater \  adj = 16 \sqrt{258}

cosθ = \frac{16 \sqrt{258} }{257} &#10;
tanθ = \frac{1}{16 \sqrt{258} }
cos<span>θ = </span>16 \sqrt{258}

SIMPLIFY 7/10+1/4-1/5=
Strike441 [17]

Answer:

3/4

Step-by-step explanation:

Q = \frac{7}{10} +\frac{1}{4} -\frac{1}{5}      

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q =\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}

=\frac{14}{20} +\frac{5}{20} -\frac{4}{20}

=\frac{14+5-4}{20}

=\frac{15}{20}

=\frac{3×5}{4×5}

=\frac{3}{4}
