depends on the needed measurement and type of triangle.
The measurement of the angle of the triangle...supposing it is a triangle.
If the triangle is equilateral, you don't have a problem, but if not you have to measure the sides.
the area referrers to the length and circumference of the triangle it self. The measurement matters to find the acute angle it self as a angle not a triangle
Regardless of whether the "other measurement" is an angle or the length of something, that much information is never enough to define anything else about the triangle.
An equalateral triangle doesn't have a measurement because each side just has to be the same. It can be an measurement. The triangle's degree's is always 360.
Volume is a measurement for 3 dimensional objects. A triangle is a 2-dimensional object. The area of a triangle is (base)x(height)/2
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
It is an isosceles triangle
By rearranging Pythagoras' theorem from a2+b2 = c2 to c2-a2 = b2 whereas a and b are the sides of the triangle with c being its hypotenuse or longest side
The formula to calculate the area of a triangle is (base/2) x height... therefore the are of the triangle in this case is 18 square inches
It is an isosceles triangle and the 3rd angle is 72 degrees.
