Answer:
X= 19.9
Step-by-step explanation:
SOH CAH TOA
x is hypotenuse
Opposite is 15
Opposite & hypotenuse - sin
Sin(49) = o/h
Sin(49) = 15/h
xh
Sin(49) x h = 15
÷Sin(49)
h = 15 ÷ Sin(49)
h=19.8751949
Hope this helps!
Complementary angles add up to 90 so 90-29=the complement, which is 61.
Answer:
dh/dt = 0,07 ft/min
Step-by-step explanation:
The swimming pool has the shape of right circular cylinder, therefore its volume is
V(c) = π*x²*h
Where x is the radius of the base and h the height
We take differentiation on both sides of the equation to get:
dV/dt = π*x²*dh/dt
The rate of change in height of water in the pool, is independent of the height of the water, since the pool is a right crcular cylinder, and dV/dt is constant at 8 ft³/min.
Then:
8 = π*x²*dh/dt
dh/dt = 8 / π*x²
dh/dt = 8/113,04
dh/dt = 0,07 ft/min
