If sinx is approximately 0.2588, what is the measurement of x to the nearest degree? Approximately, what is the cosine of the angle that is complementary to x?
+1904 \(sin(x)=0.2588\)
\({sin}^{-1}(sin(x))={sin}^{-1}(0.2588)\)
\(x={sin}^{-1}(0.2588)\)
\(x≈14.99887030548°\)
\(x≈15°\)
The complementary of angle \(15°\):
\(90°-15°=x\)
\(75°=x\)
\(x=75°\)
\(cos(75°)=x\)
\(0.258819045103≈x\)
\(x≈0.258819045103\)
