Answer: x=14
Step-by-step explanation:
First let's find all the inner angles of the triangle.
124+DCB=180 ==> Angles DCB and 124 lie on a straight line. Straight lines measure 180 degrees and are called straight angles.
124+DCB=180
124-124+DCB=180-124
DCB=180-124
DCB=56 degrees
6x+CBD=180 ==> straight angle
2x+CBD+56=180 ==> total degrees of a triangle is 180 degrees
6x+CBD=2x+CBD+56 ==> they both equal 180
6x+CBD-CBD=2x+CBD-CBD+56
6x=2x+56
6x-2x=2x-2x+56
4x=56
4x/4=56/4
x=14
