WebBecause m∠ABE and m∠C both equal 52°, ∠ABE ≅ ∠C. By the Refl exive Property of Congruence (Theorem 2.2), ∠A ≅ ∠A. So, ABE ∼ ACD by the AA Similarity Theorem. b. You know ∠SVR ≅ ∠UVT by the Vertical Angles Congruence Theorem (Theorem 2.6). The diagram shows RS — UT —, so ∠S ≅ ∠U by the Alternate Interior WebThe measure of angle BAC can be calculated using the equation sin-1 (3.1/4.5) = x. What is the measure of angle BAC?
