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:
60
Step-by-step explanation:
Assuming that all 54 shelves hold the same number of books its just a matter of dividing them (or sharing them equally) on each shelf.
3240 / 54 = 60
Each shelf holds 60 books.
Answer:
p > -18
Step-by-step explanation:
-2/3p - 4 < 8
-2/3p < 12
p > 12 x -3/2
p > -18
Answer:
40 A
Step-by-step explanation:
E=I.R ==> I=E/R
if E=6 and R=0.15 then:
I= (6/0.15)= 40 A
