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
Answer: oops 375 idk what happend

Answer:
so I think its 138 bowls so ya cause 6 times 23 is 138
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
Adding 4 to both side is wrong he has to be subtract 4 to both side
