WebCalculate the unknown angles in the following figure. Solution ∠ 47 0 and ∠ b are vertical angles. Therefore, ∠ b is also 47 0 (vertical angles are congruent or equal). ∠47 0 and ∠ a are supplementary angles. Therefore, ∠a = 180 0 – 47 0 ⇒∠a = 133 0 ∠ a and ∠ c are vertical angles. Hence, ∠ c = 133 0 Example 2
