Answer:

Step-by-step explanation:
According to congruent chords and arcs theorem, if
then
.
This means that
Thus:
(full circle = 360°)



Plug in the values into the equation


Add like terms

Subtract 36 on both sides


Divide both sides by 12

The length is 7 and the width is 3
Answer: x = 2/13
Step-by-step explanation:
9x-8=34x-12
Add 12 on both sides and you get
9x+4=34x
Subtract 9x from both sides and you get
4=26x
Divide 26 from both sides to get
X= 4/26
Simlify
x = 2/13
8 * 24 feet = 192 sq feet per 5 hours
12* 36 = 432 square feet
432 is 2.25 times the area of 192 square feet
So, it takes 5 * 2.25 = 11.25 hours
