Answer:
28.5 PLEASE GIVE ME BRAINLIEST
Step-by-step explanation:
(7 x 18 + 45) ÷ 6
171 ÷ 6 = 28.5
Fifteen divided by three is 18
1.65
1.65
1.65
4.95
all together they have that much :). I hope this helped!
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
The answer would be 208 if you find the area of each quadrilateral and add them together.
