Answer:
5. Obtuse angle and angle measurement- 130
6. Obtuse angle and angle measurement- 110
Step-by-step explanation:
If you look at the protractor you can see the numbers and if its right of the 90 degrees than its acute if its left of the 90 degrees than its obtuse. If its 90 degrees exactly then its a right angle. And you look at the numbers below the line to find the measurement and look where the line is exactly, then thats your measurement. Hope this helped!
