Answer:
hence cos ( 2 A ) = cos 2 A − ( 1 − cos 2 A ) = 2 cos 2 A − 1
Step-by-step explanation:Well we know that for two angles A , B
it holds that cos ( A + B ) = cos A cos B − sin A ⋅ sin B hence for A = B you get cos ( 2 A ) = cos 2 A − sin 2 A But sin 2 A = 1 − cos 2 A
Answer:
∠g = 142°
Step-by-step explanation:
∠g = 180 - 38 = 142°
Answer:
2<r
Step-by-step explanation:
Since they are the winning team, that means they scored more runs than the losing team. Thus, r will always be greater than 2.
