Answer:
Since 81° is less than 90, we can express this in terms of a cofunction. sin(θ) = cos(90 - θ) sin(81) = cos(90 - 81) sin(81) = cos(9)
Step-by-step explanation:
<span>-5(4x-2)=-2(3+6x)
First use the distributive property on</span>-5(4x-2) and -2(3+6x)
<span>-5(4x-2)=-2(3+6x)
-20x + 10 = -6 - 12x
Now combine like terms
</span>-20x + 10 = -6 - 12x
-20x + 12x = -6 - 10
Now finish simplifying
-20x + 12x = -6 - 10
-8x = -16
-8x / -8 = -16 / -8
x = 2
Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ± 
= ± 2
The number is - 2 or 2
