Question

The sum of the interior angles of a triangle is sometimes, but not always , 180 degrees

Answer 1

The correct answer is TRUE.

Explanation:

Find the measure of x.

Begin by setting up an equation of the five angles equal to 180°.

x + 37° + 41° + 29° + 51° = 180° • The sum of the angles is 180°.

x + 158° = 180° • Add the known values on the left side.

x = 22° • Subtract 158° from both sides.

The measure of angle x is 22°.

Answer 2

180 degrees

Explanation:

The sum of all the interior angles in a triangle is always equal to 180 degrees.
