Angles

OpenStudy (jonaho):

OpenStudy (irrati0nal):

So, triangles add up to a total of 180 degrees. Here you have a 55 degree angle and a 90 degree angle. Add these together and subtract that number from 180 and you'll find your answer.

OpenStudy (irrati0nal):

Okay, so which ones can we eliminate?

OpenStudy (jonaho):

I'm not sure

OpenStudy (jonaho):

compass

OpenStudy (irrati0nal):

Yeah, and a calculator isn't going to help much for drawing either, so we can eliminate that too.

OpenStudy (irrati0nal):

So we're left with protractor and ruler. It first tells us to find 11 cm, so which tool would be better to use to figure how far 11 cm is?

OpenStudy (jonaho):

Ruler?

OpenStudy (irrati0nal):

Right.

OpenStudy (jonaho):

Thank you

OpenStudy (jonaho):

OpenStudy (irrati0nal):

I'm happy to help. Let me know if you need help with anything else.
