Ответ:
B) 46.67°
Step-by-step explanation:
Step 1 : Write the cosine formula to find the angle C
c² = a² + b² - 2ab cos C
Step 2 : Substitute the values in the formula
6² = 7² + 8² - 2(8)(7) cos C
cos C = 0.6875
C = cos^-1 (0.6875)
C = 46.567 °
Step 3 : Round off to 2 decimal places
Angle C = 46.57°
