The central angle has a measure of radians calculated by the formula for radian measure is 1.75 radians.

<h3>What is the formula for radian measure?</h3>

The formula for radian measure to calculate the central angle is given as,

\theta=\dfrac{s}{r}

Here, (r) is the radius of the circle and (θ) is the central angle.

In a circle having a radius of 12 cm and intercepting an arc of 21 cm. Put the value of radius and the length of the arc in the above formula as,

\theta=\dfrac{21}{12}\\\theta=1.75

Thus, the central angle has a measure of radians calculated by the formula for radian measure is 1.75 radians.

PLEASE HELP THIS IS A TIMED QUESTION ON A QUIZ!!!
pantera1 [17]

Answer:

  • a)  11, d) 25, e) 14, b) 25, c) 28, f) 33

Step-by-step explanation:

<h3>Given</h3>
  • ΔBDF, with H is the centroid of BDF, DF = 50, CF = 42, and BH = 22
<h3>To find</h3>
  • HE , DE , CH, EF,  HF, BE
<h3>Solution</h3>

As per definition of the centroid, the points C, E and G are midpoints of respective sides and the length of short and long distances from the centroid have ratio of 1/3 and 2/3 of median

  • a) HE =  1/2BH = 1/2(22) = 11
  • d) DE =  1/2DF = 1/2(50) = 25
  • e) CH =  1/3CF = 1/3(42) = 14
  • b) EF =  DE = 25
  • c) HF =  2/3CF = 2/3(42) = 28
  • f) BE =BH + HE = 22 + 11 = 33

Inessa05 [86]

Answer:

for(j = n; j > 0; j--)

System.out.print(\"*\");

Step-by-step explanation:

-A for loop is a repetition control structure.

-It allows the efficiency to write a loop that would otherwise be written a couple of times.

-The output is a single line comprising n asterisks,

-The number of asterisks printed will be equivalent to the n-value declared.

(question 31) if arc mBC =120 and arc mAD =50 whatis the measure of angle DYC
g100num [7]
<h3>Answer:  D) 95</h3>

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

Explanation:

First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:

angle BYC = (arcAD + arcBC)/2

angle BYC = (50+120)/2

angle BYC = 170/2

angle BYC = 85 degrees

Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)

angleBYC + angleDYC = 180

angleDYC = 180 - angleBYC

angleDYC = 180 - 85

angleDYC = 95 degrees

which is why the answer is choice D.
