If cos x is approximately 0.4226, what is the measurement of x to the nearest degree?
Approximately what is the sine of the angle that is complementary to x.

A.25; 0.9063
B.25; 0.4226
C. 65; 0.9063
D. 65; 0.4226

Respuesta :

Answer:

D.

Step-by-step explanation:

IF cos(x)=0.4226 then [tex]x = cos^{-1} (0.4226) = arc(0.4226)[/tex] ⇒ x=65° so Compl. x = (90° - x) = 25⁰, finally sin (25⁰) = 0.4226
