Question

If angle 2 measures 155 degrees in the image below and what is the measurement of angle 1

Answer 1

Angle 1 measures 25 degrees

Step-by-step explanation:

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the diagram shown below. In that figure, we know that:

`\angle 1=? \\ \\ \angle 2=155^(\circ)`

The figure shows that these two angles are supplementary, so they add up to 180 degrees. Therefore:

`\angle 1+\angle 2=180^(\circ) \\ \\ Substituting \ \angle 2=155^(\circ): \\ \\ \angle 1+155^(\circ)=180^(\circ) \\ \\ \\ Isolating \ \angle 1: \\ \\ \angle 1=180^(\circ)-155^(\circ) \\ \\ \boxed{\angle 1=25^(\circ)}`
