Answer:

<u>108°</u>

Step-by-step explanation:

Formula :

<u>Degree Measure = Arc length / radius x 180/π</u>

Solving :

Degree Measure = 3π/5 x 180/π

Degree Measure = 3 x 36

Degree Measure = <u>108°</u>

Answer:

108°

Step-by-step explanation:

\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle in degrees)}

Given:

  • diameter = 10 km ⇒ radius (r) = 5 km
  • Arc length = 3π km

Substituting the given values into the formula and solving for \theta:

\implies 3 \pi=2 \pi (5)\left(\dfrac{\theta}{360^{\circ}}\right)

\implies 3 =10\left(\dfrac{\theta}{360^{\circ}}\right)

\implies 3 \cdot 360^{\circ} =10\:\theta

\implies \theta=\dfrac{1080^{\circ}}{10}

\implies \theta={108^{\circ}

Find the value of x, rounded to the nearest tenth. <br> Answer options: 3.8, 4, 2.7, 2.9
Masteriza [31]

Answer:

4

Step-by-step explanation:

If two chords intersect externally, then the product of the length of the chord and the length of the part outside the circle is a constant.

Thus from the figure,

we can deduce that:

8×3=6×x

collecting the like terms together we get:

24=6x

x=4

Solve for x. Please:)
lutik1710 [3]

Answer:

  x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

  8/4 = (8 +(x -1))/5

  10 = x +7 . . . . . . . . . multiply by 5 and simplify

  3 = x . . . . . . . . . subtract 7

__

<em>Alternate solution</em>

The short segments are also proportional:

  (x -1)/(5 -4) = 8/4

  x -1 = 2 . . . . simplify

  x = 3 . . . . . . add 1

All you have to do is multiply the whole number by the denominator and add the numerator. For example:

5 3/6 5*6 is 30 +6 is 36

therefore the improper fraction is 36/6
