# Some of the angles that are obtained when two lines intersect are equal to 30 degrees. What are the other angles?

| From the condition, we know that one of the angles formed at the intersection of two straight lines is 30 °.

So, let’s first of all remember what angles are formed when two straight lines intersect.

When straight lines intersect, vertical angles are formed – they are equal to each other. Adjacent corners are also formed.

In our problem, we are talking about adjacent corners. Their sum is 180 °.

Then the unknown angles will be denoted by the variable x;

x + 30 = 180;

x = 180 – 30;

x = 150 °;

So, one pair of vertical angles is 30 °, and the second is 150 °

Answer: 30 °; 30 °; 150 °; 150 °.
