How Do You Find a Missing Angle in a Right Triangle?

Find the value of x in the figure.

Summary

  1. A right angle is an angle measuring 90°.
  2. A right triangle is a triangle with an angle measuring 90°.
  3. The measurements of all 3 angles of a triangle add up to 180°.
  4. Angle D and angle F must be complementary, since together with the right angle A, they add up to 180°.
  5. Solve for the value of x by subtracting 16° from both sides to get x by itself.

Notes

    1. A triangle is a polygon with 3 sides and 3 angles.
    2. A right angle is an angle measuring 90°.
    3. A right triangle is a triangle with an angle measuring 90°.
    1. The measurements of all 3 angles of a triangle add up to 180°.
    2. Complementary angles are angles that add up to 90°, and the angles that touch the hypotenuse in a right triangle happen to be complementary!
