It depends where the X is.
If you want the end across from the right angle, check out this answer.
The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.
The given dimensions are not compliant for the construction of a right angle triangle but the area of any triangle is: 0.5*base*height
if the triangle has one right angle in it
First find the area of the square (length x width) then find the area of the triangle (base x height x 2) and add the two answers together.Quadrilateral just means "four sides", but the sides have to be straight.Assuming it's a right-angle triangle? Such a triangle is half of a rectangle or square, so times by 2).
(base x height) / 2
That depends on what x is: a leg, an angle, what?
you go get a calculator

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
A right angle triangle has a 90 degree angle with two acute angles and the 3 interior angles add up to 180 degrees
If it has no right angles, it is not a right triangle and therefore you cannot name a hypotenuse of that triangle. Which implies you cannot find that side's measure.
right
drop a line from the vertex to the bottom line of the triangle you get a right angle triangle with side 6, 3 and x where x is the altitude of the triangle 6^2=3^2+x^2 use pythagoreus theorem 36=9+x^2 x=sqrt 27=3sqrt3=5.196cm
