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 °.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
