Since 9 is closer to 10 than 0, we round up.
Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
Here,
Angle F = 180 – ( 90 + 60 )
Or, Angle F = 180 – 150
Or, Angle F = 30 °
Here,
- Angle G is directly proportional to the Side EF.
- Angle F is directly proportional to the Side GE.
- Angle E is directly proportional to the side FG.
Now,
EF = 10√2 Units
Then, FG = 60 / 90 × 10√2
Finally, EG = 30 / 90 × 10√2
Hence,
A very quick way of solving this problem is to recognize and use the fact that a line parallel to 5x-2y=2 has an equation which is exactly the same as 5x-2y=2 except for the constant.
Replace that 2 (on the right side of the equation) with C, and x with -4, and y with -3:
5(-4)-2(-3)=C
and find C. C = -20 + 6 = -14.
Therefore, the equation of the line parallel to 5x-2y=2 passing thru the point (-4, -3) is 5x-2y= -14. Notice how only the constant changes.
