In a triangle, 2 angles are equal to 27 and 79, find its 3 angle in degrees.

To find out what the third corner of the triangle is, you should remember the rule.
According to the rule, the sum of the three sides of a triangle is 180 °.
Let’s write down what is the sum of the angles of this triangle.
Moreover, let this triangle be a triangle ABC with angles A, B and C.
A + B + C = 180 °.
Let’s express the angle C.
C = 180 ° – (A + B).
By hypothesis, it is known that the angles A and B are respectively equal to
Substitute these values into the above equality.
C = 180 ° – (27 ° + 79 °).
C = 180 ° – 106 °.
C = 74 °.
Answered: 74 °.
