simple...
first we know that a triangle has a sum of 180 degrees therefore you add the two known angles then subtract their sum from 180 which gives you the measure of the third angle

How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
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.
Relations among the angles of a triangle?
In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
What is the measure of an angle in an equiangular triangle?
The sum of the internal angles in a triangle is equal to 180 degrees. An equiangular triangle, otherwise known as an equilateral triangle, has three angles of the same length, and three angles of the same size. The size of each angle is 180 / 3 = 60 degrees.
How do you find a missing angle for a triangle?
Subtract the two known angles from 180 degrees will give you the missing angle
How do you determine the third angle of a triangle if 2 angles are known?
There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C
What is the angle that is not congruent to the base angles of an isosceles triangle?
The sum of the internal angles of a triangle is 180 degrees. If you know the size of the angles at the base of an isosceles triangle, the final angle can be found by subtracting the size of the two known angles from 180.
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
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.
What is angle sum property of a triangle?
The sum of the three interior angles of a triangle is always 180 degree is known as angle sum property of a triangle.

In a triangle, the sum of the angles is always 180 degrees. This is known as the angle sum property of triangles. Additionally, the largest angle in a triangle is always opposite the longest side, and the smallest angle is opposite the shortest side.
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
What is the measure of an angle in an equiangular triangle?
The sum of the internal angles in a triangle is equal to 180 degrees. An equiangular triangle, otherwise known as an equilateral triangle, has three angles of the same length, and three angles of the same size. The size of each angle is 180 / 3 = 60 degrees.
How do you find a missing angle for a triangle?
Subtract the two known angles from 180 degrees will give you the missing angle
How do you calculate the missing degree of a triangle?
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
How do i find the value x in a scalene angle?
If it is a scalene triangle then: 180 - the sum of the 2 known angles = x angle
What type of shapes have 2 obtuse angles?
Example 1: A right triangle has one other angle that is 35º. What is the size of the third angle? Solution: Step 1:A right triangle has one angle = 90°. Sum of known angles is 90° + 35º = 125°. Step 2:The sum of all the angles in any triangle is 180º. Subtract sum of known angles from 180°. 180° - 125° = 55° Answer:The size of the third angle is 55°
