We know that

[length of a circumference ]=2*pi*r
for r=1 units
[length of a circumference ]=2*pi*1------> 2*pi units

if 2*pi radians (full circle) has a length of-----------------> 2*pi units
pi/3 radians-----------------------------> X
X=(pi/3)*2*pi/(2*pi)-----> pi/3 units

the answer is
pi/3

Answer : 50 degree

To find angle 1 , we apply outside angle theorem . Refer to the diagram attached below.

Measurement of arc EF=140 degrees

Measurement of arc GH = 40

Angle D = angle 1

Theorem says

$angle D = \frac{arc(EF)-arc(GH)}{2}$

Now we plug in the values

$angle 1 = \frac{140-40}{2}$

angle 1 = 50

Measurement of angle 1 = 50 degrees

Find the x-intercept of parabola with vertex (1,-17) and y-intercept (0,16)?

Ad libitum [116K]

Y=a(x-1)^2 -17 is the equation of the parabola.
at (0,16), 16=a(0-1)^2 -17. Solve for a = 33.
Equation is then y=33(x-1)^2-17 so when y=0,
(x-1)^2 = 17/33
x-1 = + and - square root of 17/33
x = 1.7177 and 0,2823 as the intercepts
