An angle whose measure is _____ is rotated more than halfway around a circle
zaharov [31]

The correct answer is 60⁰.

Step-by-step explanation:

  • An angle whose measure is 60⁰ is rotated more than halfway around a circle.
  • Since, we have to find the measure of angle.  
  • As we already know that the angle of rotation about a circle is 360° therefore we have to find more than halfway of this angle.
  • Considering that an angle is rotated more than halfway around a circle be \frac{1}{6}
  • Multiplying \frac{1}{6} with 360⁰
  • Therefore, it can show as \frac{1}{6}×360⁰
  • Which gives the result to be 60⁰
  • Hence, when an angle is measured 60⁰, it is rotating more than halfway around a circle.
  • A single rotation around a circle is equal to 360 degrees.
  • The measurement of an angle shows the magnitude and direction of the rotation of the angle from its initial position to the final position.
  • If the rotation is in a counterclockwise direction, it has an angle with positive measure. If the rotation is clockwise, it has an angle which gives negative measure.

Calculate the length of BE
lora16 [44]

Answer:

BE = 72 cm

Step-by-step explanation:

\frac{AB}{BC} = \frac{BE}{CD}        (BPT Theorem)

\frac{20}{5} = \frac{BE}{18} \\

⇒ 4 = \frac{BE}{18}

⇒BE = 18 × 4

∴ BE = 72 cm

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.
kotegsom [21]

Answer: (-9, 16]

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

-2 < x \le 3

5(-2) < 5x \le 5(3)

-10 < 5x \le 15

-10+1 < 5x+1 \le 15+1

-9 < 5x+1 \le 16

This converts to the interval notation  (-9, 16]

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
