What is Cos 15?
The cosine of 15 degrees can be calculated using the cosine subtraction formula: ( \cos(15^\circ) = \cos(45^\circ - 30^\circ) ). This gives us ( \cos(15^\circ) = \cos 45^\circ \cos 30^\circ + \sin 45^\circ \sin 30^\circ ). Plugging in the known values, ( \cos 45^\circ = \frac{\sqrt{2}}{2} ), ( \cos 30^\circ = \frac{\sqrt{3}}{2} ), ( \sin 45^\circ = \frac{\sqrt{2}}{2} ), and ( \sin 30^\circ = \frac{1}{2} ), we find that ( \cos 15^\circ = \frac{\sqrt{6} + \sqrt{2}}{4} ).

What is the interior angle of a 19 sided shape?
To find the interior angle of a polygon with ( n ) sides, you can use the formula ((n - 2) \times 180^\circ) for the sum of the interior angles. For a 19-sided shape, the sum of the interior angles is ((19 - 2) \times 180^\circ = 17 \times 180^\circ = 3060^\circ). To find the measure of each interior angle in a regular 19-sided polygon, divide the total by 19: (3060^\circ / 19 \approx 160^\circ). Thus, each interior angle is approximately (160^\circ).

How do you work out the interior angles of a 25 sided polygon?
To find the interior angles of a 25-sided polygon (icosikaipentagon), you can use the formula for the sum of interior angles, which is ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a 25-sided polygon, this calculation would be ( (25 - 2) \times 180^\circ = 23 \times 180^\circ = 4140^\circ ). To find the measure of each interior angle in a regular 25-sided polygon, divide the total sum by the number of sides: ( \frac{4140^\circ}{25} = 165.6^\circ ).
