Let the second angle of the triangle be A.
Then angle 1 = 2A : and angle 3 = 3A - 12
The internal angles of a triangle total 180° therefore :-
2A + A + (3A - 12) = 180
6A - 12 = 180 : 6A = 192 : A = 32
The angles measure 64° , 32° and 84° .

What is the measure of the third angle of a triangle if two angle measures 42 degrees?
96˚all angles to a triangle equals 180˚
What is the measure of the third angle of a right triangle if one of the angles measures 50 degrees?
The other acute angle in that triangle is 40 degrees.
How do you classify a triangle by its angles?
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
If two angles of a triangle each measure 45 degrees what is the third angle?
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
which is the inverse of the following conditionalAll scalene triangles have three angles with distinct measures.?
If a triangle is not scalene, then the triangle does not have three angles with distinct measures.
If the sum of the measures of two angles of a triangle is equal to the measure of the third angle the triangle must be?

What is the measure of the third angle of the triangle if the measures of two angles of a triangle are 35deg and 45deg?
The missing angle measure is 100 degrees.
What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
The measure of an exterior angle of a triangle is equal to the sum of the measures of its?
