Answer:
1800
Step-by-step explanation:
Explanation: The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with twelve sides, so we will let n = 12. The sum of the interior angles in this polygon would be 180(12 – 2) = 180(10) = 1800.
PLEASE SAID THANKS
we know that
In a right triangle
the value of the cosine is equal to
and the value of the sine is equal to
so
<u>First case</u>
substitute
therefore
The first case is the solution
<u>Second case</u>
substitute
therefore
The second case is not the solution
<u>Third case</u>
<u>Note The hypotenuse cannot be smaller than the adjacent leg or the opposite leg. This problem has errors </u>
substitute
therefore
The third case is not the solution
the solution is the first case

A system of equations with one polynomial function of degree two and one linear function will have two solutions when the line intersects the parabola at two points.
A system of equations with one polynomial function of degree two and one linear function will have no solution when the line does not intersects the parabola.

8100/6 = 5400/x
cross multiply
8100x = 32400
x = 32400/8100
