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
Step-by-step explanation:
-5x+y+9-4x-8y+11
-9x-7y+20
Answer:
Distributive property is to divide because the meaning of "distribute" is to divide something or part of something.
Example: 3(4+8) = 36
You have to add the numbers first before multiplying since there are parenthesis. Usually, in the distributive property you will always see parenthesis.
I can’t help because I can’t see the coordinate plane.
