18. Adding Angles
Nate and Sam played 5 rounds of Angle Tangle. Nate drew the following types of angles for
Sam.
1 reflex angle, 1 right angle, 1 acute angle, and 2 obtuse angles.
Both Nate and Sam were very good at estimating the measures of angles. Their total scores
for the game were so close that the boys decided on another way to choose the winner.
They decided to add the measures of their 5 angles, and the one who had the greatest sum
would win.
Sam’s angles totaled 625º.
What could the measures of his 5 angles be? Show or explain how you found your answers.
