What is the sum of the interior angles of an 8 sided convex polygon?
Take the number of sides and subtract 2, then multiply that answer by 180. (8-2) x 180 = 6 x 180 = 1080
What is the third angle in a triangle if the other two are 38 degrees and 95 degrees?
180-38-95. The sum is always 180 in a triangle, so just subtract the other two from 180 to get the third.
Sum is to add as what is to subtract?
When you add, your answer is the sum.When you subtract, your answer is the difference.
What is the sum of angles in a octadecagon?
( n x 180 ) - 360wheren is the number of sides.In other words,take the number of sides or your polygon and multiply that by 180.then, subtract 360 from that result.that is your answer.An octadecagon has 18 sides.( 18 x 180 ) - 360 = 2880The sum of the interior angles of an octadecagon is 2880 degrees.
Find the measure of the third angle?
In euclidean (plane) geometry, the sum of the interior angles of any triangle is 180 degrees. Add the two angles you know (right angles = 90 degrees) and subtract that sum from 180. Without more information on the problem, that's the most I can assume
