What trigonometric function has the same value as sin 75?

1 answer:

5 0

Cosine and Sine are related by the formula cos(x)= sin(x+90). Setting x+90 equal to 75 results in x=-15, Therefore, cos(-15) = sin (75). Since cos is an even function, cos(15)=cos(-15)= sin(75).

Answer:

Option D

Step-by-step explanation:

$F=\frac{9}{5}C+32\\\\F-32=\frac{9}{5}C \\\\5(F-32)=9C\\\\\frac{5(F-32)}{9}=C \\\\C=\frac{5}{9}( {F-32})$

For F=77°F

$C=\frac{5}{9}(F-32) \\\\C=\frac{5}{9}(77-32)\\\\C=\frac{5}{9}(45)\\\\C=\frac{225}{9} \\\\C=25$
