The recorded angle measurements of ∠BAC and ∠CAD could be 110° and 70°, vice versa.
What are supplementary angles?
Supplementary angles are a pair of angles that always sum up to 180°. These angles can either;
Adjacent supplementary angles
Adjacent supplementary are angles with a common vertex and arm.
Non-adjacent supplementary angles
Non- adjacent supplementary angles are angles without a common vertex or arm.
∠BAC and ∠CAD are adjacent supplementary angles because they have a common vertex, A, and a common arm AC.
They add up to 180°.
∠ BAC = 110° and ∠CAD = 70°
Hence, the angles could be 110° and 70°.
