Snow often melts as it lands. your welcome!
Answer:
6, 3
Step-by-step explanation:
Answer:
-90 , 30
Step-by-step explanation:
sina = cos(2a)
= 1 - 2(sina)^2
2(sina)^2 + sina -- 1 = 0
( sina + 1 )( 2sina - 1 ) = 0
sina = -1 or sina = 1/2
=> a = -90 degrees or => a = 30 degrees
Answer:
x = - 1.10 and x = 1.10
Step-by-step explanation:
Given
25x² - 30 = 0 ( add 30 to both sides )
25x² = 30 ( divide both sides by 25 )
x² = 
( take the square root of both sides )
x = ± 
x = - 1.10 and x = 1.10 ( to the nearest hundredth )
