Calculate The Mean Measure Of The Exterior Angles Of A Triangle. Find the measure of the exterior angle - 18628392. 2 3 6 8 11.
Set up an equation with the sum of the three angles equating it with 180 and solve for x. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. We know that the three interior angles of any triangle always add up to 180 degrees.
This means we can add the 64 and 45 together and subtract that from 180 to find the.
