Math Problem Statement

What is m∠AOC if m∠AOB = 47° and m∠BOC = 59°?

Solution

To solve for mAOCm \angle AOC, we can use the fact that the sum of adjacent angles around a point OO is 180180^\circ. Specifically:

  • mAOB=47m \angle AOB = 47^\circ
  • mBOC=59m \angle BOC = 59^\circ

Since we are looking for mAOCm \angle AOC, we know:

mAOC=mAOB+mBOCm \angle AOC = m \angle AOB + m \angle BOC

Substitute the given values:

mAOC=47+59=106m \angle AOC = 47^\circ + 59^\circ = 106^\circ

Thus, the measure of AOC\angle AOC is 106 (no degree symbol as requested).
