Answer:
30 meters away
Step-by-step explanation:
each second is equal to 5 meters, hence meters per second
Answer:
the tip is $10.17 which means the total is $82.80
Step-by-step explanation:
Siplify
6/3=2
so
n-2=-4
ad 2 to both sides
n+2-2=-4+2
n+0=-2
n=-2
It is 100 degrees because angles z and w need to equal 180 and a triangles angles always answer 180 degrees with angle y being 20 and an 80 degree angle making angle z 80 degrees making angle w 100 degrees.
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
