I'm fairly certain the answer is 1/3.
Answer:
d
Step-by-step explanation:
Answer:
384
Step-by-step explanation:
8 x 6 = 48
48 x 2 = 96
12 x 10 = 120
6 x 12 = 72
8 x 12 = 96
96 + 120 + 72 +96 = 384
Answer:
140, 60
Step-by-step explanation:
15x+5 + < CDB =180 line form an 180 angle
180-80-6x-6 = < CDB sum of angles in a triangle is 180
substitute < CDB from second to first
15x+5+180 -80-6x-6 =180
combine like terms
9x -81 =0
x=81/9=9
so angle YDC = 15*9+5 = 140 degrees
and angle DBC = 6*9+6= 60 degrees
