So, Cot is negative in second and fourth quadrant.
So, tan(x+
)=-cot(x)
Option B
Answer:
Step-by-step explanation:
Side Opposite to ∠x is called YZ
The side Opposite to ∠y is called XZ (that's the hypotenuse of the triangle)
Side Opposite to ∠Z is XY
Aneesha is traveling at a rate of 4400 feet per second, which means that Morris is traveling a a rate of 4397 feet per second
Area of sandbox = 169 square feet
Area of square with side 'x' is given by the formula = 
We have to determine the total length of wood Drew needs to make the sides of the sandbox.
Total length of wood required would be equal to perimeter of sandbox.
Let 'a' be the side of the square sandbox.
So, Area of sandbox = 169


a = 13 feet
Total length of wood required to make sides of the sandbox = Perimeter of the square sandbox = 
= 
= 52 feet.
Therefore, 52 feet of wood is required to make the sides of the square sandbox.
Answer:
x=8a
Step-by-step explanation:
3/a x-4=20
We need to solve for x
Add 4 to each side
3/a x-4+4=20+4
3/a x = 24
Multiply each side by a/3 so we can get x alone
a/3 *3/a x = 24 * a/3
x = 8a
