Answer:
Step-by-step explanation:
If COP and TOD are vertical angles, then they are equal to each other because vertical angles are equal.
m COP = m TOD
Given
COP = 11x - 17
TOD = 9x + 11.
Substitute:
11x-17 = 9x+11
11x-9x = 11+17
2x = 28
x = 28/2
x = 14
Get <COD
<COP = 11(14)-17
<COP = 154-17
<COP = 137
<COD = 180-<COP
<COD = 180-137
<COD = 43°
Similarly:
<POT = 180 - <TOD
<POT = 180 - [9(14)+11]
<POT = 180 - 137
<POT = 43°
Answer:
5 minutes
Step-by-step explanation:
let the time after which two lines will have filled an equal number of barrels is 'X' minutes.
so, according to the question after 'X' minutes;
⇒ number of barrels in old conveyer line = number of barrels in new conveyer line
⇒
⇒
Answer:
<1 = 12.71 degrees
<2 = 77.29 degrees
Step-by-step explanation:
<1 = x
<2 = 6x - 1
x + 6x - 1 = 90 degrees
7x = 90 - 1
x = 89/7
x = 12.71
The answer is 56 square meters
