Answer:

Step-by-step explanation:
1 has been divided into three equal parts. Each of these parts is 1/3. Let's calculate how many times 1/3 is in 3.
Answer:
Step-by-step explanation:
5.25 - 2.625 = 2.625 inches
Answer:
Step-by-step explanation:
12x - 3 = 180 - (7x - 26) supplementary angles
19x = 209
x = 11
m∠DEC = 12(11) - 3 = 129°
m∠BCE = 7(11) - 26 = 51°
M∠ADE = 129 - 72 = 57° exterior angle rule
m∠EDB = 180 - 57 = 123° supplementary angles
m∠DBC = 57° corresponding angle to ADE
A. x-6=6
if u plug in 12, you get 12-6=6 which is true
all the other ones would be false if you plugged in 12
