hello :)
ΔABC ~ ΔFED
, this because
∠A=∠D
∠B=∠E
∠C=∠F
Answer:
8
Step-by-step explanation:
√(64)
Angle x is the same as the angle opposite it so 63 degrees
angle y = 180 - 72 - 63 = 45 degrees
angle z is the same angle shown at point B so 72 degrees
Answer:
If we are assuming that this is a direct variation, y would be equal to 99.
Step-by-step explanation:
To find this, we start with the base equation for direct variation.
y = kx
Now we find k by plugging in our original values for x and y.
y = kx
36 = k(4)
9 = k
Now that we have k, we can model the equation.
y = 9x
And we can use the value of 11 in the next equation to find y.
y = 9x
y = 9(11)
y = 99
Answer: The length of the second arc is 12 feet.
Step-by-step explanation:
Since we know that
A rope is swinging in such a way that the length of the arc is decreasing geometrically,
Length of first arc = 18 feet
Length of third arc = 8 feet
Let the length of second arc be x
As we know that
Hence, the length of the second arc is 12 feet.
