The sine and cosine of acute angles are equal only for 45°
sin45° = cos 45° = 1/sqrt(2) = 0.7071

at a 45 degree angle, or pi/4
Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
it is a acute angle because acute angles are less than 90degrees so basically the answer is............ 0.602 mayo.fo.sho
√ 1/2 = sine(45)= cosine(45) -Key
