WebNov 28, 2024 · Figure 5.28.2. Solution. y is an exterior angle and all the given angles add up to 360 ∘. Set up an equation. 70 ∘ + 60 ∘ + 65 ∘ + 40 ∘ + y = 360 ∘ y = 125 ∘. Example 5.28.4. What is the measure of each exterior angle of a regular heptagon? Solution. Because the polygon is regular, the interior angles are equal. WebAnswer (1 of 3): The clue to understanding polygons (regular to be complete) is to calculate the exterior angle. Continue the lines of the polygon to see these exterior angles and note as we go round 360 degrees we get back to our first exterior angle. So we can deduce each angle is 1/7 of 360 ... WebNov 28, 2024 · In geometry, you must know that any heptagon, whether regular or not,the sum of all its interior angles is 900°. Having 7 sides, there are also 7 interior angles. Let's write down the algebraic equation using x as the unknown angle of the other interior angles. 900 = 135(4) + 3x Solving for x, x = 120° irb international corporation
