Angles and Lines

Forgive us for being obtuse, but this is a cute concept, and we think it’s right for you. See more

Level 3


In the figure above, 3 unit squares are placed side by side. Find the sum of the angle measurements \(a,\) \(b,\) and \(c,\) in degrees.

Find \(x\) (in degrees).

Lines \(l\) and \(m\) are parallel. \(M\), \(N\) and \(O\) are points such that \(M\) is on \(l\) and \(N\) is on \(m\) and \(O\) is between the two lines. If the smaller angle between \(l\) and \(MO\) is \(35^{\circ}\) and \(\angle MON = 105^{\circ}\), find the acute angle between \(m\) and \(NO\).

Determine the value of \(x\).

What is the angle between the two green lines?
