Step-by-step explanation:
Angle G = 180° - 48° - 75° = 57°
By Sine rule, FG/sinD = DG/sinF = DF/sinG.
Hence DF = 22.57 units and DG = 25.99 units.
Answer:

Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to

we have


substitute


step 2
we know that
The area of a circle subtends a central angle of 2π radians
so
using proportion
Find out the area of a sector with a central angle of 8 π/11 radians

So,

That means the person would pay $14,400 on a property worth $800,000.
I bag covers 2500 soft.
Rectangular lawn is 410 x 65. Area= lw=(410)(65)=26650
26650/2500=10.66 so since we cannot purchase .66 of a bag, we will need 11 bags.
