Convert 2pi/3 to degrees

2 answers:

4 0

So we're converting a radian to a degree.

So we'll do 2pi/3 times 180/pi. The pi's cancel out and the 3 and 180 and be simplified to 60. You're then left with 2 times 60 which gives you your answer of 120 degrees.

LK is tangent to circle J at point K. Circle J is shown. Line segment J K is a radius. Line segment K L is a tangent that inters

Evgen [1.6K]

Answer:

$(B)r=\dfrac{85}{12}$

Step-by-step explanation:

Given a circle centre J

Let the radius of the circle =r

LK is tangent to circle J at point K

From the diagram attached

LX=6
Radius, XJ=JK=r
LK=11

Theorem: The angle between a tangent and a radius is 90 degrees.

By the theorem above, Triangle JLK forms a right triangle with LJ as the hypotenuse.

Using Pythagoras Theorem:

$(6+r)^2=r^2+11^2\\(6+r)(6+r)=r^2+121\\36+6r+6r+r^2=r^2+121\\12r=121-36\\12r=85\\r=\dfrac{85}{12}$

The length of the radius, $r=\dfrac{85}{12}$

15 POINTS!!!!!!! What is the equation of the line in slope-intercept form? Line on a coordinate plane. Line runs through points

suter [353]

Answer:

$y=\frac{4}{3}x+4$ is the equation of line in slope intercept form.

Step-by-step explanation:

Line runs through points begin ordered pair negative 3 comma 0 end ordered pair and begin ordered pair 0 comma 4.

First ordered pair: (-3,0)

Second ordered pair: (0,4)

We have two points and need to find equation of line in slope intercept form

$\text{Slope (m)}=\dfrac{y_2-y_1}{x_2-x_1}$

$\text{Slope (m)}=\dfrac{4-0}{0-(-3)}=\dfrac{4}{3}$

y-intercept, when x=0 , (0,4)

Equation of line in slope intercept form:

y=mx+b

where, $m=\frac{4}{3}$ and b=4

Required equation:

$y=\frac{4}{3}x+4$

Thus, $y=\frac{4}{3}x+4$ is the equation of line in slope intercept form.
