Answer:
Option A. -(
)
Step-by-step explanation:
Equation of a given line is a + 4b = 0 or b = -
This in the form of y = mx + b, which is slope-intercept form.
Here slope of the line is (
).
Or tanθ = 
This line coincides with the terminal side of the angle in standard position where cosθ > 0
Since tanθ = 
and sinθ = 
Hypotenuse = 
= 
= 
Since tanθ is negative and cosθ > 0 that means θ lie in fourth quadrant.
Therefore, sinθ will be negative.
[ 
]
sinθ = -
= -
Answer will be option A.
Answer:
b = (a - 6)/2h
Step-by-step explanation:
a = 2bh + 6 (subtract 6 from both sides)
a - 6 = 2bh (divide both sides by 2)
(a - 6)/2 = bh (divide both sides by h)
(a - 6)/2h = b

Step-by-step explanation:
Answer:is there another triangle or is it just that one?
Step-by-step explanation:
Answer:
A = 9x² + 48x + 65
Step-by-step explanation:
Area of a Square Formula: A = lw
Since a square's length is equal to its width, we simply plug it into the formula:
A = (3x + 8)(3x + 8)
Then we simply use FOIL to expand the distribution)
First - 3x(3x) = 9x²
Outside - 8(3x) = 24x
Inside - 8(3x) = 24x
Last - 8(8) = 64
Lastly, we combine like terms
9x² + 24x + 24x + 64
9x² + 48x + 64
