Calculate the following expression:

[tex]\[
\sin (90^\circ - 25^\circ) = ?
\][/tex]


Sagot :

Sure, let's go through this step-by-step.

1. Calculate the angle:
[tex]\[ 90^\circ - 25^\circ = 65^\circ \][/tex]

So, we need to find the sine of [tex]\(65^\circ\)[/tex].

2. Evaluate the sine of the angle:
[tex]\[ \sin(65^\circ) \approx 0.9063 \][/tex]

Therefore, [tex]\(\sin (90-25)^{\circ} = \sin(65^\circ) \approx 0.9063\)[/tex].
