Ok well right now in California its 5:34 and its probably 8:34 in Miami. Because the sun is not in the same elevation. Depending on longitude and position there is a time difference that was calculated by a system. Based on simple mathematics and subtraction you can conclude that the time difference between Miami and California is 3 hours<span />
Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
By using trigonometric relations, we will find that:
sin(θ) = (√33)/7 = √(33/49)
<h3>How to find the value of the sine?</h3>
Remember that for a right triangle, we have the relations:
cos(a) = (adjacent cathetus)/(hypotenuse)
sin(a) = (opposite cathetus)/(hypotenuse).
Here we know that:
cos(θ) = 4/7
Then we can say that we have a triangle with an adjacent cathetus of 4 units and a hypotenuse of 7 units. Now we need to find the other cathetus.
opposite cathetus = √(7^2 - 4^2) = √33
Then we can write:
sin(θ) = (√33)/7 = √(33/49)

Answer:
86.7 ft²
Step-by-step explanation:
arc area = area of the circle x ( arc angle measure / 360°)
area of the circle = 65 / (270/360) = 86.67 ft²
