WebThe sum of interior angle in a triangle is 180º. An equilateral triangle has 3 angles of equal size. Therefore each interior angle is 60º because 180 ÷ 3 = 60. Therefore one exterior angle is equal to 180 – 60 because the interior angle and exterior angle of a polygon lie on a straight line. Therefore one exterior angle is 120º. Weby = 40°. Therefore, the values of x and y are 140° and 40°, respectively. Example 3. The exterior angle of a triangle is 120°. Find the value of x if the opposite non-adjacent interior angles are (4x + 40) ° and 60°. Solution. Exterior angle = sum of two opposite non-adjacent interior angles. ⇒120° =4x + 40 + 60.
WebRight triangles are triangles in which one of the interior angles is 90 degrees, a right angle.
