How do i find the remaining angles without a protractor?
schepotkina [342]

Answer:

<u>For Triangles:</u>

To find remaining angles, implying that you have angles already given to you, you would mark your unknown angle as a variable, x per say, then you would add together the angles that you do have and you would subtract that by 180 degrees because all triangles angles sum up to 180 degrees. So when you subtract that you should be able to find your unknown angle.
