Adjacent angles measuring 65° and 115° are supplementary, forming a straight line with a total angle sum of 180° as shown in the diagram representation below.
What are adjacent angles?
The adjacent angles measuring 65° and 115° are labelled as angle a and angle b respectively in the image below.
In this representation, the angle on the left measures 65° (angle a), and the angle on the right measures 115° (angle b). Angles a and b share a common arm, and their vertices are at the same point.
The relationship between angles a and b can be characterized as supplementary of the sum of their measures is 180°. In this case: 65° + 115° = 180°
So, the angles are supplementary, and together they form a straight line.
