Total interior angles ((2 x 7) - 4) right angles ie 900 degrees. Given angles total 570 degrees so each of the other angles is (900 - 570)/2 ie 165 degrees.

Q: If five angles of a heptagon have measures of 80 degrees 85 degrees 175 degrees 90 degrees140 degrees and if the other two angles are congruent what is the measure of each of the other two angles?

The sum of the measures of the interior angles of a heptagon is 900 degrees.

A heptagon has 7 sides and 7 angles. The sum of the interior angles is 900°. If the heptagon is a regular heptagon, meaning all sides and angles are congruent, then the formula (180(n-2))/ n gives the individual interior angle measure. "n" is the number of sides in this case. In a regular heptagon, the interior angle measures 128 4/7 degrees.

900 degrees.Explanation: The sum of the measures of the interior angles of a heptagon is 900°. A heptagon has 7 sides. So to calculate the sum of the measures of the interior angles in a heptagon, substitute 7 for n in (n − 2) • 180°. You get (7 − 2) • 180°, or 5 • 180°= 900°.

To find the sum of the interior angles of a heptagon, use the formula (n-2) times 180 over n, where n is equal to the number of sides of the polygon.For a heptagon, which is a 7-sided figure, we plug in values to get (7-2) times 180, or 5 times 180 degrees, or 900 degrees.

An interior angle of a heptagon can have any value in the range (0, 360) degrees - other than 180 degrees.
