Question

Four of the angles of a pentagon measure 85°, 110°, 135°, and 95°. Find the measure of the missing angle.
115°
95°
135°
85°

Answer 1

Max angles of a polygon are given by: 180(n-2) where n is number of sides:

So: for a pentagon = 5 sides.

180(5-2) = 180*3 = 540 degrees

Then, subtract the four angles and you get: 540 - 110 - 95 - 85 -135 = 115 degrees for missing angle.
