180 - 64.6 - 18.7 = 96.7 degrees
you add it all
ABC angle is an angle,not a triangle!

It could be a right triangle if it has a right angle (90 degrees). If it does not have a right angle, then it is an acute triangle.
The measurement of the angle of the triangle...supposing it is a triangle.
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
It is an isosceles triangle and the 3rd angle is 72 degrees.
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.
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.
A right triangle has one 90-degree angle.
The 3rd side of the right angle triangle can be found by using Pythagoras' theorem.
depends what type of triangle you are measuring sorry :)
No because a right angle is a measurement of 90 degrees.
Interior angle+exterior angle = 180 degrees

90 Degrees
