The sum of two criss-crossing angles is 150 degrees. The degree measure of each angle is …

From the condition, we know that the sum of two intersecting angles is 150 °. And we need to find the degree measure of each angle.

Let’s first recall the definition of criss-crossing angles.

Internal criss-crossing corners are pairs of angles that are formed at the intersection of two straight secant lines that lie in the inner region on opposite sides of the secant line.

We also need to know their properties to solve the problem. And specifically the following – the angles lying crosswise are equal to each other.

That is, to find their degree measure, we will do this:

150 °: 2 = 75 °.
