How do you work out the base of an isosceles triangle?
Using trigonometry. The Hypotenuse x The height
What is x of a right triangle when the hypotnuse is 12.1 and an angle is 39?
The answer depends on what x is. And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer. Further Information:- Using trigonometry the sides of the right angle triangle work out as 9.403466134 and 7.614776732 or about 9.4 and 7.6
How do you work out the inside angle of a triangle using trigonometry?
The answer depends on what information you do have. If you have all three sides, you use the cosine rule to find any one of the angles and then use the sine rule to find the other two.
What is theta?
It is a greek letter which is used to mark an unknown angle in a triangle when you are going to use trigonometry to work it out, eg. sin(theta)=length of opposite side/ length of hypoteneuse
How is trigonometry helpful?
Trigonometry is helpful in many fields of geometry and a few of them are:- It helps to identify different types of triangles It helps to work out the sides and interior angles of triangles It helps to work out the properties of polygons It helps to work out the properties of a right angle triangle with Pythagoras' theorem It helps with navigating and working out distances
What is the angle that a right angle triangle has?
The angle directly opposite the hypotenuse is always 90o in a right angle triangle and if you know the other sides you can work out the other angles using one of the three trigonometry equations. Sin, Tan or Cos then use the inverse and you will get the degree.
How do you work out an angle using trigonometry?
The answer depends on what else you know about the shape.

When is the earliest evidence of greek work in math or trigonometry?
Pythagoras was an ancient Greek mathematician who found fame with his theorem for a right angle triangle which states that for any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
What is is the formula called that you can use to work out a side length of a right angle triangle?
The general term is trigonometry. What specific formula you use depends on what other information you have.

It is a greek letter which is used to mark an unknown angle in a triangle when you are going to use trigonometry to work it out, eg. sin(theta)=length of opposite side/ length of hypoteneuse

What are the angles of a triangle that has sides of 5.4cm by 7.1cm by 8.3cm?
Using the cosine rule in trigonometry the angles work out as 40.11 degrees, 57.9 degrees and 81.99 degrees
How do you work out exterior angle for a triangle?
It is: 180-interior angle = exterior angle
Where does Pythagoras's rule not work?
Pythagoras's Rule does not work if the triangle is not a right angle triangle, that is having one angle equal to 90 degrees. (The rule can still be applied by creating right angles along one or more sides, using lines perpendicular to the side.)
