To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.
We are given that angle A has a measure of 120 degrees and angle B has a measure of 34 degrees.
To find the measure of the third angle, we can subtract the sum of angles A and B from 180 degrees:
180 degrees - 120 degrees - 34 degrees = 26 degrees
Therefore, the measure of the third angle of the triangle is 26 degrees.
To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.
We are given that one angle measures 34.6 degrees and another angle measures 52.8 degrees.
To find the measure of the third angle, we can subtract the sum of the given angles from 180 degrees:
180 degrees - 34.6 degrees - 52.8 degrees = 92.6 degrees
Therefore, the measure of the third angle of the triangle is 92.6 degrees.
To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.
We are given that one angle measures 63 degrees and another angle measures 40 degrees.
To find the measure of the third angle, we can subtract the sum of the given angles from 180 degrees:
180 degrees - 63 degrees - 40 degrees = 77 degrees.
Therefore, the measure of the third angle of the triangle is 77 degrees.
To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.
We are given that one angle measures 40 degrees and another angle measures 65 degrees.
To find the measure of the third angle, we can subtract the sum of the given angles from 180 degrees:
180 degrees - 40 degrees - 65 degrees = 75 degrees.
Therefore, the measure of the third angle of the triangle is 75 degrees.
We know that the sum of the angle measures in a triangle is always 180 degrees.
So, we can set up the equation:
75° + 41° + (3x + 19)° = 180°
Combining like terms:
116° + 3x + 19° = 180°
Simplifying:
3x + 135° = 180°
Subtracting 135° from both sides:
3x = 45°
Dividing both sides by 3:
x = 15°
Therefore, x is equal to 15 degrees.
To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.
Given that one angle measures 25 degrees and another angle measures 68 degrees, we can subtract the sum of these angles from 180 degrees to find the measure of the third angle:
180 degrees - 25 degrees - 68 degrees = 87 degrees.
Therefore, the measure of the third angle of the triangle is 87 degrees.
Use the Triangle Angle Sum Theorem to find the measure of the third angle of the triangle if the measure of two angles are 34.6° and 52.8
A triangle has angle measures of 75°, 41°, and (3x+19)°. Solve for x.
