Question

8) Answer below and show all work. (3 points) 4.5x a.) What does x equal? b.) What is the measure of ABC? c.) What is the measure of 2DBC?, D W​

Answer 1

see explanation

Explanation:

(a)

∠ ABC and ∠ DBC are a linear pair and sum to 180° , that is

6.5x + x = 180

7.5x = 180 ( divide both sides by 7.5 )

x = 24

(b)

∠ ABC = 6.5x = 6.5(24) = 156°

(c)

∠ DBC = x = 24°
