Gina looked at the triangle above and noticed that two acute angles added together equals to 90o. 53 + 37 = 90. Using this info, she wrote C + G = 90. She concluded: Since G = 90 - C, sin G = sin (90 - C) and cos G = cos (90 - C) Since C = 90 - G, sin C = sin (90 - G) and cos C = cos (90 - G) Is her conclusion true?
