X = 45 is the answer
180-x = 3(90-x)
=> 180-x = 270 - 3x
=> -x+3x = 270-180
=> 2x = 90
=> x = 90/2
=> x = 45

Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.

Answer: I believe the race is 8/8 long
Step-by-step explanation: Because the race is 1/4 long and 1/4 is 1/8 mile the entire race is 8/8 miles
The vertex is the point where the function changes direction, in this case from growing to decrease. That is the point wiht x-coordinate 4 and y-coordinate 1, so the point is (4,1).
