Answer 1

Hey people! I just wanted you to know that I don't really have the exact steps for you but I have the answer.

Approximate answer: 16 degrese

Step-by-step explanation: in ΔBCD, start overline, B, D, end overline BD is extended through point D to point E, m, angle, B, C, D, equals, left bracket, 3, x, plus, 14, right bracket, degreesm∠BCD=(3x+14) ∘ , m, angle, C, D, E, equals, left bracket, 9, x, minus, 17, right bracket, degreesm∠CDE=(9x−17) ∘ , and m, angle, D, B, C, equals, left bracket, 3, x, plus, 20, right bracket, degreesm∠DBC=(3x+20) ∘ . Find m, angle, D, B, C, .m∠DBC.
