Answer:

Look at image I attached below.

Explanation:

Important points to memorize when finding missing angles like these:

  • Two angles directly across from each other, not next to, are equal.
  • All angles that are on one side of a straight line add up to 180°, because a straight line has an angle measure of 180°.
  • A full spin-around equals 360°.
  • All angles in any triangle add up to 180°.

When you know all these important rules, the rest is just a matter of adding and subtracting.
