M_6 is (2x – 5)º and m_8 is (x + 5)º.

What is m 3?

Q: I can’t seem to figure out the equation. Could someone explain step by step and give a link to a video like Kahn Academy to explain? I’m lost !

m_6 + m_8 = 180º because they form a straight line.

So, (2x-5) + (x+5) = 180

3x = 180

x = 60

So, m_115º (2•60 - 5 = 115)

Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.

So, m_3 = 115º
