Use the relationship between the angles in the figure to answer the question.
Anuta_ua [19.1K]

Answer:

37+x+53 = 180

x=90

Step-by-step explanation:

To find x, we need to use the fact that a straight line equals 180 degrees.

37+x+53 = 180

Combining like terms

90+x = 180

Subtract 90 from each side

90-90+x = 180-90

x = 90

The water level, measured in feet above mean sea level, of Lake Lanier in Georgia, USA, during 2012 can be modeled by the functi
FrozenT [24]

Answer:

May 4th, 2012.

Step-by-step explanation:

The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:

l'(t) = 0.04323\cdot t^{2}-0.8354\cdot t +2.703

l''(t) = 0.08646\cdot t - 0.8354

The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.

0.04323\cdot t^{2}-0.8354\cdot t +2.703 = 0

Roots are t_{1} \approx 15.672 and t_{2} \approx 4.077. just the second root offer a realistic solution and is test by the second derivative.

l''(4.077) = -0.482 (which leads to a maximum).

Given that a year has 365 days or 12 months, the highest water level occurs at day:

n = \frac{4.077}{12} \cdot (365\,days)

n \approx 124 (May 4th).
