The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180.
The measure of each interior angle of an equiangular n-gon is.
If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.
354 as a percentage is 354%
35.4 as a percentage is 35.4%

Theorem
The measure of an exterior angle of a triangle equals the sum of measures of the remote interior angles.
Angle STV is an exterior angle of triangle SRT.
The two remote interior angles to exterior angle STV are angles S and R.
Since the triangle is isosceles, with sides ST and TR equal, angles S and R are equal, so they both measure 27 deg.
<STV = 27 + 27
<STV = 54
