Answer:
d = 2cot(x) or d = 2/tan(x)
Step-by-step explanation:
The vertical distance from the jet to the top of the house represents the opposite side to the 'x' angle, while the horizontal distance, d, represents the adjacent side. Since we do not know the hypotenuse, the tangent and cotangent functions are the preferable choices:
Therefore, the distance 'd' can be expressed as d = 2cot(x) or d = 2/tan(x).
-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x
Answer:
12 inches
Step-by-step explanation:
A square has 4 sides with the same length.
The perimeter of a square is the 4 times the length of one side.
perimeter = 4s
perimeter = 4 * 3 inches
perimeter = 12 inches
Y = 4x + 3 ---------(1)
y = -x - 2 ---------(2)
Subtract (2) from (1), you get
0 = 5x + 5
⇒ 5x + 5 = 0
⇒ 5x = -5
⇒ x = -5/5 = -1
y = -(-1) - 2 = -1
Answer is (-1,-1)
