Since the other angle that right next to it, the same angle you equal both angles together.

4x = 68.

We want to get x by its self. There is a 4 with the x and they're multiplying. to get rid of 4 we need to the opposite of multiplying which is division on both sides of the equation.

4x = 68
/4      /4

4 divided by 4 is 1 and 68 divided by 4 is 17

x = 17 is the answer.
If you plug in x = 17 into 4x, it will be 68

Length of the diameter =   sqrt ( (-12- (-8)^2) +(2-0)^2) )
  = sqrt  (16 + 4) = sqrt20 
so radius = sqrt 20 / 2 = sqrt5
so r^2 = 5


Center of the circle = coordinates of the midpoint of the diameter =

-8-12/2 , 2-0 / 2  =    (-10, 1)

(x - a)^2 + (y - b)^2 = r^2  is general form of a circle so here the circle is:_

(x + 10)^2 + (y - 1)^2 = 5  Answer

A 290-kg flatcar 28 m long is moving with a speed of 6.5 m/s along horizontal frictionless rails. A 95-kg worker starts walking
blsea [12.9K]

Answer:

9.33 seconds

60.67 meters

Step-by-step explanation:

A worker with a speed of 3.0 m/s with respect to a car, starts to walk from one end of the car to the other in the direction of motion of the car.

As the car is 28 m long, then the worker will reach the other end of the car in \frac{28}{3} = 9.33 seconds. (Answer)

Now, the car is moving with a speed of 6.5 m/s and in the time of 9.33 seconds, it will move by 6.5 \times 9.33 = 60.67 meters. (Answer)
