You must use the formulas you know that describe the properties of triangles
to relate the information you're given to the size of the unknown angle.
Do you want to know the measurement / size of the angle.
The internal angles of a triangle add up to 180 degrees. If you know two angles then add them together
eg 60 + 30 = 90 now subtract 90 from 180, 180-90 = 90
So the missing angle is 90 degrees
Subtract the two known angles from 180 degrees will give you the missing angle
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle.
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
If they are the angles of a triangle then the missing angle is 116 degrees
no because an equilateral triangle is a total of 180 degrees not 120. but if you need to find the missing angle or missing degree then yes!
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.

the missing angle is 93 degrees. you find that out by adding 53 and 34 and then subtracting them from 180. :)

all the angles in a triangle have to add up to 180. to find the missing angle : 180 - 32 - 58 = 90 90 is a right angle and since there is a right angle in the triangle, it is a right angled triange
The sum of all the angles in a triangle equals 180o. To find the missing angle, subtract the sum of the two known angles from 180o.ExampleTwo angles of a triangle are 35o and 62o. What is the third angle?Solution180o - (35o + 62o) =180o - 97o = 83o
If that's a right angle triangle then the missing angle is 58 degrees
When placed next to any angle on a triangle, the theta symbol (θ) represents that missing angle.
