Answer:
0.9212 (Answer b)
Step-by-step explanation:
Note that sin 52 deg 47 min = sin (52 47/60 deg)
Using the fact that pi radians = 180 degrees, convert the argument of the sine function to radians:
sin ( [52 47/60][pi rad][180 deg] )
= sin ( 0.2932 pi) = 0.9212
Using a calculator to evaluate this, we get 0.2891
Answer is 800/p
800 is the number of planks divided by how many she paints a day to calculate the number of days.

Below is the solution:
10:4 = 6:x
<span>10/4 = 6/x </span>
<span>10x = 24 </span>
<span>x = 2.4</span>
SInce you need 1.5 feet of overhang, add 3 feet to each axis dimension 1.5 on each side):
Minor Axis = 18 + 3 = 21 feet
Major axis = 25 + 3 = 28 feet
The area of an ellipse is found by multiplying half the minor axis by half the major axis by PI.
1/2 minor axis = 21 / 2 = 10.5
1/2 major axis = 28 / 2 = 14
Using 3.14 for PI
Area = 10.5 x 14 x 3.14 = 147 x 3.14 = 461.6 sq ft
