All the angles together equal 180, so take the two known angles and subtract them from 180.

How do you find the third angle of a scalene triangle?
If you have the other two angles, you can subract them from 180 degrees, which is the sum of the angles in any triangle.
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
What are the angles for a right angle?
A right angle, by definition, is 90 degrees. If you mean what are the other angles in a right triangle, you need one of the other angles in the triangle or the length of one side (not the hypotenuse) any two sides. You can then find the third side by Pythagoras, then the other two angles by simple trigonometry.
How do you find the measure of an angle in a triangle when the measures of the two other angles are known?
Well the three angles in a triangle all add up to 180° so if you add the two known angles and take it away from 180 you'll get your unknown angle.
How do you find the 3rd angle in a triangle?
It is: 180-angles 1 and 2 = angle 3

Ratio of the angles in a triangle?
if the angle of a triangle are in the ratio 7:11:18,find the angle

Well the three angles in a triangle all add up to 180° so if you add the two known angles and take it away from 180 you'll get your unknown angle.
What is the measure of a triangle if one angle measures 57 degrees?
The inner angles of a triangle will always add up to 180. Assuming that this particular triangle is a right triangle (that is, one of it's angles is 90 degrees), you can find the other angle by subtracting the known angles from 180: 180 - 57 - 90 = 33 degrees If the triangle is an equilateral or a scalene triangle, the other angles cannot be calculated without additional information.
How do you find the 3rd angle in a triangle?
It is: 180-angles 1 and 2 = angle 3
If the vertex angle of an isosceles triangle has a measure of 108 what is the base angle?
In an isosceles triangle two of the sides are equal, as well as two of the angles. Because a triangle's interior angles add up to 180, only one angle could be 108, therefore the other two angle must be equal. To find the measure of the other two angles 180 - 108 = 72/2 = 36.
How do you find the missing angle of a triangle if you are given two of the angles?
180 minus two known angles = unknown angle
What is the angle measure for a triangle?
The angle measure of a triangle is dependent on the type of triangle (scalene, right, isosceles, or equilateral) and also the measures of the other two angles.In a scalene, none of the angles can be predicted without a protractor because none of the angles are equal.In a right triangle only one angle can be undoubtedly determined, the 90° angle (right angle). Knowing this angle's measure, this only limits the possible angle measures of the other two angles. (They must each be less than 90°, but together sum up to 90°)If you know one of the base angles of an isosceles triangle, by the Isosceles Triangle Base Angles Theorem, the other base angle will be congruent. To find the last angle, add the base angles together and then subtract that number from 180.The only triangle that has angle measures that can be determined just by its name is an equilateral, all angle measures equal 60°.
How do you find the measure of 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.
How do you find the x and y angles on a right triangle?
A right angle triangle has a 90 degree angle with two acute angles and the 3 interior angles add up to 180 degrees
