WebCalculator Use. From the source of Khan Academy: Trig values of special angles. We know that the measure of an acute angle is less than a right angle, i.e. Every angle is measured from the positive part of the x-axis to its terminal line (the line that determines the end of the angle) traveling counterclockwise. In an acute triangle, the following statement holds good for the length of the sides: Where a, b and c are the sides of a triangle. The measure of an angle which is greater than 90 degrees (right angle) and less than 180 degrees is called obtuse angle. They are equal to the ones we calculated manually: = 51.06 \beta = 51.06\degree = 51.06 , = 98.94 \gamma = 98.94\degree = 98.94 ; additionally, the tool determined the last side length: c = 17.78 i n c = 17.78\ \mathrm{in} c = 17.78 in .
