Answer:
800mph
Step-by-step explanation:
divide 1800 by 2 1/4
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tan x =
, sin²x + cos²x = 1
Consider the left side

=
← multiply numerator/ denominator of the whole fraction by cos²x
= 
= 
= cos²x - sin²x
= cos²x - (1 - cos²x)
= cos²x - 1 + cos²x
= 2cos²x - 1
= right side , thus proven
3/6 + 3/6 = 6/6
2/6 + 4/6 = 6/6
1/6 + 5/6 = 6/6
