... m∠3 = 180° 3 2 1 – THE GRE QUANTITATIVE SECTION 184 Example: mЄ1 = mЄ3 + m 5 mЄ4 = mЄ2 + m 5 mЄ6 = mЄ3 + mЄ2 ■ The sum of the exterior angles of a triangle equal to 360 degrees. Triangles More ... 180. Thus, the equation is x + x + 10 = 180. Solve for x:2x + 10 = 180 –10 –10 2x = 170 ᎏ 2 2 x ᎏ = ᎏ 17 2 0 ᎏ x = 85 Therefore, mЄx = 85 and the obtuse angle is equal to 180 – 85...
