Q1 of 23 Page 22

Select the correct alternative and fill in the blank in the following statements.

In ΔABC∠ A =760, ∠ B = 480, ∠ C = …

∠ A + ∠ b + ∠ C = 180° (the sum of the measures of the interior angle of a triangle is 180°

∠ A + ∠ B + ∠ C = 180°


∠ 76 + ∠ 48 + ∠ C = 180°


∠ 124 + ∠ c = 180°


∠ C = 180-124


∠ C = 56°
