The third angle is 93 degrees
The answer would actually be 40 because180-140=40.
It depends on what measure is missing.
Measure it with a ruler.

Add together the given angles, or the angles you already know or have been given measures for, and then subtract the added numbers from 180 and that is you answer.
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° .
It depends on what measure is missing.
The measures of two angles in a triangle are shown in the diagram. Which equation can be used to find the value of x?
Each of the remaining two angles is 32.5degrees.(32.5) + (32.5) + (115) = 180
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
