WebJun 23, 2011 · or. Note: We could also find the sine of 15 degrees using sine (45° − 30°). sin 75°: Now using the formula for the sine of the sum of 2 angles, sin ( A + B) = sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees. We now find the sine of 36°, by first finding the cos of 36°. WebExpert Answer.
