Question

2) If 25 and 26 are supplementary angles, and m25 = 124°; find m26.

Answer 1

Two angles are said to be supplementary if the sum of their measures is 180 degrees.

Given that angles 25 and 26 are supplementary,

`\angle25+\angle26=180`

Also it is given that the angle 25 measures 124 degrees.

Substitute the value,

`\begin{gathered} 124+\angle26=180 \\ \angle26=180-124 \\ \angle26=56 \end{gathered}`

Thus, the angle 26 measures 56 degrees.
