Question

I need help with finding interior/exterior angles. solve for “?”

Answer 1

Answer:

3. 160

4. 105

5. 95

6. 30

7. 86

8. 130

All triangles equal 180 so when you add the other 2 degrees in the triangle then subtract that by 180 then you get the third angle. The a straight line also equals 180 degrees so when you get the third angle subtract it by 180 then you get the answer to the "?"

That's how I was taught so, hope I got it all right! : )
