It depends on the triangle in question. Angle C is not 50 in all cases!

triangle ABC with rigth at C
What type of figure (polygon) are we referring to' you do not say. Assuming you mean a triangle. Then the sum of the interior angles of a triangle is 180 degrres. Hence A + B + C = 180 Substituting A + 42 + 27 = 180 Subtract '42' & '27' from both sides A = 180 - 42 -27 A = 138 - 27 A = 111 degrees.
As we know that all angles of a triangle = 180 degrees So, Angle A + Angle B + Angle C = 180 degrees So, 100 + 17 + x = 180 Angle C = 180 - 117 Angle C=63 degrees
'a' and 'b' must both be acute, complementary angles.
55 degrees.
