These formulas allow you to express the exact value of trigonometric expressions that you could not otherwise express. Consider the sin(105°). Unlike the sin(30) which can be expressed as ½, the sin(105) cannot simply be represented as a rational expression. However, the angle sum formul...
Use the Pythagorean theorem to find out a side's length and afterwards calculate its opposite angle (since angles are proportionate to the sides' length). According to the theorem, the square of side opposite to the right angle (hypotenuse) equals the sum of the squares of the other two si...
Calculate the sine of this angle by dividing the measurement of the opposite side by the measurement of the hypotenuse. For example using the angle formed by a hypotenuse of 13 and a leg of 5 requires you to divide the opposite side,12, by the hypotenuse,13, for a sine of 0.923. Calcu...

In order to find the measure of a single interior angle of a regular polygon (a polygon with sides of equal length and angles of equal measure) with n sides, we calculate the sum interior anglesor (n−2)⋅180(n−2)⋅180 and then divide that sum by the number of sides or nn...
So theta = arcsin(3/5) = arccos(4/5) = arctan(3/4) = 36.87°. This allows us to calculate the other non-right angle as well, because this must be 180-90-36.87 = 53.13°. This is because the sum of all angles of a triangle always is 180°. ...
