Let tree's height = h
h/80 = tan 30
⇒ h = 80 tan 30
⇒ h = 80 * 1/√3
⇒ h = 46.19 ft
I believe 11 centimeters is the answer.
Y=-6(10)+15
y=-60+15
y=-45
y=-120+15
y=-105
range equals -105 to 45
Answer:30.48
Step-by-step explanation:
The length of an arc is the fraction of its circumference based on the given intercepted angle. This is given by the equation,
L (arc) = (Angle / 360) x 2πr
Substituting the known values,
L (arc) = (40 / 360) x 2π(8 inch) = 16π/9 inch
Thus, the length of the arc is approximately equal to 5.585 inches.
