One of the adjacent angles is 142 degrees. find the second corner.

The desired unsettled second angle is determined using the conditional variable “Y”.
Based on the information of the problem and knowing that the sum of adjacent angles is 180 °, we will form the following expression: Y + 142 = 180.
The result of the calculation made will be equal to Y = 180 – 142 = 38 °.
Answer: 38 °.
