Question

using the diagram below if the measure of ange 1 is equal to 45 degrees what is the measure of angle 2?

Answer 1

The angle 1 and 2 forms the linear pair on a straight line.

The value of angle 2 can be determined as,

`\begin{gathered} \angle1+\angle2=180^(\circ) \\ 45^(\circ)+\angle2=180^(\circ) \\ \angle2=180^(\circ)-45^(\circ) \\ \angle2=135^(\circ) \end{gathered}`

Thus, the value of angle 2 is 135 degrees.
