Answer:

62°

Step-by-step explanation:

Since one arm making angle x is diameter. So, by inscribed angle theorem, we have:

x =  \frac{1}{2} (180 \degree - 56 \degree) \\  \\  x=  \frac{1}{2}  \times 124 \degree \\  \\  \huge \red{ \boxed{x = 62 \degree}}

Plot and connect the points A (2, -2), B (-4, -4), C (-4, -1), D (-2, 3), E (1, 3), F (2, 5), and find the length of BC.
Paul [167]

Answer:

BC = 3 units

Step-by-step explanation:

Given points:

  • A = (2, -2)
  • B = (-4, -4)
  • C = (-4, -1)
  • D = (-2, 3)
  • E = (1, 3)
  • F = (2, 5)

<u>Plot the points</u> on the coordinate plane (x, y) and connect them in alphabetical order with straight lines (see attached).

From visual inspection of the <u>drawn polygon</u>, we can see that the length of BC is 3 units.

It is fairly simple to calculate the length of BC without plotting the points.

As points B and C have the same x-value, this means that the distance between them is simply the difference between their y-values.

⇒ distance = |-4 - (-1)| = |-3| = 3 units

A train travels 110 km in the same time that a plane covers 385 km. If the speed of the plane is 20 km per hr less than 4 times
slamgirl [31]

Answer:

  • train: 40 kph
  • plane: 140 kph

Step-by-step explanation:

Let t represent the speed of the train in km/h. Then 4t-20 is the speed of the plane. Travel times are the same, so we can use the formula ...

  time = distance/speed

and equate the travel times.

  110/t = 385/(4t-20)

Cross multiplying gives ...

  110(4t -20) = 385t

  440t -2200 = 385t . . . . . eliminate parentheses

  55t -2200 = 0 . . . . . . . . . subtract 385t

  t -40 = 0 . . . . . . . . . divide by 55

  t = 40 . . . . . . . . . . . add 40; train's speed is 40 kph

  4t -20 = 140 . . . . . . find plane's speed; 140 kph

The train's speed is 40 km/h; the plane's speed is 140 km/h.

_____

<em>Check</em>

Train's travel time = 110 km/(40 km/h) = 2.75 h.

Plane's travel time = 385 km/(140 km/h) = 2.75 h.
