it is impossible to do because you need at least 2 angles to tell the other one
All unknown sides and angles of a triangle can be found only when one side and two angles, two sides and the included angle, two sides and an angle opposite one of them, or three sides are given.
All you will know is that the sum of the other two angels is 180 - (value of known angle).

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
How do you find out the height of a triangle if only the 3 angles are given?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
How do the properties of an isosceles triangle an equilateral triangle and a right triangle how you find the measure of unknown angles?
It works out as: 180 minus the 2 known angles = unknown angle

By using trigonometry that is applicable to a right angle triangle.
