This is not sufficient information. The angles of a triangle add up to 180o and so all that can be deduced is that the remaining angles add up to 180o-38o which is 142o.
In plane Euclidean geometry there are 3 angles in any triangle that add up to 180 degrees and if given 2 angles the sum of the 2 angles minus 180 will give the measure of the 3rd 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
I am guessing you mean you are given 2 of the 3 interior angles of a triangle and are asked for the 3rd. Well, it is a theorem that the 3 angles of a triangle add up to 180 degrees. So add the 2 given angles and subtract the sum from 180. to get the measure of the 3rd angle.
The sum of the angles of a triangle equal 180 degrees. The sum of the angles of a quadrilateral equal 360 degrees. To find the measure of an angle for a triangle, you must first be given the other two angle numbers, unless it is an equilateral triangle, in which all angles would equal 60 degrees. To find the measure of a quadrilateral, you must first be given the other three angle numbers, unless it is a square, in which all angles would equal 90 degrees.
You don't. It takes more than one side and one angle to determine a triangle. If you have two sides and the angle between them, or one side and two angles, you can do it.
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
180 minus two known angles = unknown angle

Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.

if the angle of a triangle are in the ratio 7:11:18,find the angle
One can't. The angle between those is needed.

To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
It is: 180-angles 1 and 2 = angle 3
