LC = 55°, ZD = 65°, and ZB = 2x
D
С
В B.
x = [?]

Answer 1

Answer:

x = 30

Step-by-step explanation:

65 + 55 = 120

angle B must equal 60

angle B is labeled as 2x

set up equation to solve for 'x':  2x = 60

                                                     x = 30

add up all angles to make sure you get 180 degrees
