Who is known as the father of trigonometry?
Hipparchus is the father of trigonometry and he was a Greek astronomer who lived between 190-120 B.C. He is considered as the father of trigonometry, a branch of mathematics which studies the angles of sides of triangles. :)
What is used to solve a triangle when the measure of two angles and the measure of any side are known?
Trigonometry is used depending on what the problem is.
What are the other possible angles and third side of a triangle when angle 50 degrees is facing side 25cm which has another side of 30cm?
The given question is known as an 'ambiguous case' in trigonometry and by using the sine and cosine rules in trigonometry its other angles are 66.82 degrees and 63.18 degrees with a 3rd side of 29.13cm or its other angles are 16.82 degrees and 113.18 degrees with a 3rd side of 9.44cm.
What area of mathematics is James Gregory famous for?
He is known for his significant advances in trigonometry.
Can you find the hypotenuse of a right triangle when only one side length is known and all three angles?
Yes. You will need to use trigonometry. sin (angle) = opposite/hypotenuse cos (angle) = adjacent/hypotenuse tan (angle) = opposite/adjacent
