Express sin 143o in terms of an acute angle
Weba) sin 150° The corresponding acute angle is 30°. In the second quadrant, sin θ is positive. Therefore, sin 150° = sin 30° = ½. b) cos 135° The corresponding acute angle is 45°. In … WebAn angle which is measuring less than 90 degrees is called an acute angle. This angle is smaller than the right angle (which is equal to 90 degrees). For example, ∠30 o, ∠45 o, ∠60 o, ∠75 o, ∠33 o, ∠55 o, ∠85 o, etc. are all acute angles. Let us see some examples here to understand. Example: See the figure below:

WebAnswer (1 of 2): You can subtract 90 or 360 from a large angle as many times as necessary to get an angle less than a complete cycle/circle, but that does not always give you the right value. In general, when you stop doing that, you may end up at any of 4 places in the cosine function as shown i...
