The answer will depend on how the triangle is situated within the rectangle (how many of the triangle's vertices coincide with those of the rectangle), and what other information you have.

How do you work out the angles of a triangle with only one angle?
You cannot.
How do you work out the angles in a triangle with only 3 sides and no angles?
use the inverse sine or cosine or tangent
How do Interior angles of a triangles work?
The 3 interior angles of any triangle add up to 180 degrees
How do you work out if a triangle is a scalene triangle?
When each of the 3 interior angles measure less than 90 degrees and the 3 sides are of different lengths
Can the Pythagorean theorem be used on a rectangle?
no because the algorithum states it mst be a triangle for the algorithem to work
How do you work out the angles in a right angle triangle?

Which three angle measures could represent the measures of the interior angles of a triangle?
All interior angles of a triangle MUST (a triangle by definition states that all interior angles MUST) add up to 180. Any measures would work, provided the three angles would add up to 180*....so a triangle with angles 1, 1, and 178 degrees works, as well as a triangle with 60, 60, and 60 degrees. Any angle combinations work, as long as the three angles add up to 180.

How do you work out the sum of a triangle?
A triangle has no sum. There can be a sum of the measures of two or more angles, or the lengths of two or more sides, for example.
How do you work out the value of a triangle?
A triangle does not have any particular value. There are the magnitudes of its size, its angles, its area, its perimeter etc, but no single VALUE.
What is the problem if angles are not congruent?
None! If the angles are not congruent then the shapes are not similar of congruent. But that is not a problem. The angles of an equilateral triangle are not congruent to the angles of a square but that does not mean that you cannot work with equilateral triangles or squares!
What are the angles of a triangle that has sides of 2.60cm 2.85cm and 4.70cm?
Using the trigonometrical cosine formula for a triangle the angles work out as 28.91 degrees 31.99 degrees and 119.10 degrees which add up to 180 degrees.
Is it possible to work out the other angles of a triangle given only one angle?
YesAnother Answer:-Yes under certain conditions depending on what type of triangle it is and the measure of the angle givenBut normally two angles are needed to find the third angle in a triangle
