Answer:
11 feet away.
Step-by-step explanation:
Given:
A water and sprinkle our sins water out in a circular pattern
Area formed by the watering pattern is 379.94 square feet
To find:
How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?
solution:
By using ,Area of a circle = 
Area of a circle = 379.94 square feet (given)
= 

Dividing both side by 3.14

Taking square root both side
(Taking common)

Therefore, radius = 11
Thus, it can spread water 11 feet away.
Answer
Step-by-step explanation:
Law of sines: SinB/15 = SinA/BC
B = 90
A = 180-90-21=69°
BC= (15*SinA)/SinB = (15*sin69)/1 ≈ 14m
Answer:
D.) 9m
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
ok so, assuming that b cannot equal 0, we can divide it on both sides
(3a - 5)/c = b/b
anything divided by itself is 1
(3a - 5)/c = 1
multiply c:
3a - 5 = c
3a = c + 5
a = (c + 5)/3
