| The unidentified third angle of the triangle is determined using the conditional variable “Y”.
Considering that the sum of the 3 angles of the triangle is 180 °, and applying the example data, we get the following expression: Y + 70 + 40 = 180.
Solving the composed expression, we get the following result Y + 110 = 180 or Y = 180 – 110 = 70 °.
Answer: 70 °.
