for a 90 you have to use Pythagoras rule a2+b2=c2 c been the longest side usually in front of the right angle side. For a 30 you have to use this formula 1/2absinc. ab are the two sides you know and c is the angle 30. The same thing works for 60 degree triangle also. hope i helped.
What else can I help you with?
How do you find a missing side of a triangle?
The way to find the missing side of a triangle-THIS ONLY WORKS ON RIGHT ANGLED TRIANGLES-is square both sides seperately and then add them together to give you the square of the missing side-find the square root and that is the size of the missing side-eg. if you have a RIGHT ANGLED TRIANGLE with sides of 3inch and 4inch then (3x3) + (4x4) = 25 so the square root of 25 is 5 meaning the missing side is 5inch.
How do you find a missing angle of a right triangle given two sides?
180-x-y (x and y are the sides you already know) there are 180 degrees in a triangle. The remaining # is the last angle
How do you find the are of a triangle with a missing base?
That really depends what else you know about the triangle. For example, if you only know the lengths of two sides, you simply don't have enough information.
How do you find the measure of a missing side of a triangle?
It depends on what information you do have. There are different solutions depending on whether you have two sides and the included angle, or two sides and a median, two sides and an altitude, etc.
How do you find the missing angles of a triangle with one?
you must know more information. Like the lengths of 2 sides. Then using Trig (law of sines or law of cosines) you can find the remaining sides and angles.
Find the missing side of a right triangle whose hypotenuse is 13 if one of the sides of the triangle is 5?

How do you find a missing side to a right triangle?
A triangle always has 180 units. You would have to add up the two sides and subtract that from 180.
How do you find a missing angle of a right triangle given two sides?
180-x-y (x and y are the sides you already know) there are 180 degrees in a triangle. The remaining # is the last angle
How do you find the sides of the triangle?
a triangle always has three sides
How do you find the third side of a triangle given two sides?
To create a triangle, the sum of the two shorter sides must be greater than the third side. If the longest side is one of the two given sides, then the missing side must be greater than the difference between the two shorter sides. If the missing side is the longest side then the missing side must be less than the sum of the two shorter sides.

That really depends what else you know about the triangle. For example, if you only know the lengths of two sides, you simply don't have enough information.
How do you find the missing side from a right triangle?
to find the missing side of a right triangle you need the pythagorean theorem. A2 + B2 = C2. c is the longest side and a and b is the other sides. no particular side is a or b just the longest side is c.
How do you find the measure of a missing side of a triangle?
It depends on what information you do have. There are different solutions depending on whether you have two sides and the included angle, or two sides and a median, two sides and an altitude, etc.
How do you find the missing length of a triangle?
You use the Pythagoras Theorem if it is a right-angled triangle. a squared + b squared = h (longest side, diagonal) squared, then square root h to find the longest side. if it is not a right angled triangle, then use the Sine or Cosine rule. Sine rule for: two angles and any one side or two sides and an angle that is not in between the sides. Cosine rule for: all three sides (but then you do not need to find a missing side) or two sides and an angle that is in between.
How do you find the range of a triangle?
to find the range of values of triangle. Add the value of the sides of the given sides...is it?
How do you find the missing angles of a triangle with one?
you must know more information. Like the lengths of 2 sides. Then using Trig (law of sines or law of cosines) you can find the remaining sides and angles.
