What is the length of chord An in Oo below?
Anika [276]

Answer:

12 units

Step-by-step explanation:

In\: \odot O,

  • chords \overline{ML} and \overline{AN} are equidistant (7.2 units) from the center of the circle O.
  • Measures of the chords equidistant from the center of the circle are equal.
  • \therefore m(chord\:\overline{AN}) =m(chord\:\overline{ML})
  • \because m(chord\:\overline{ML}) = 12\: units
  • \therefore m(chord\:\overline{AN}) = 12\: units

Line ET is tangent to circle A at point T and the measure of angle TNG is 35.
STALIN [3.7K]

ET is tangent to circle A so ET is perpendicular to AT

So <ATE = 90°

Given <TNG = 35°

<NET = <ATE - <TNG

= 90° - 35°

= 55°

Answer is 55°

The angle of a quadrilateral are A.P and the common difference is 10°. find the angles.
xxMikexx [17]

Step-by-step explanation:

So the Ap will be x,x+10,x+20,x+30

Sum of the angles of a quadrilateral is 360

x+x+10+x+20+x+30=360

4x+60=360

4x=300

x=75

So the angles are 75,85,95,105

Mike travels 13 miles per 2 hours on his bike.
LiRa [457]

Answer:

It took Markus half an hour to drive home from work.  He averaged 34 miles per hour.  How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip.  This is a time:

       t  =  1/2

We are given that he averages 34 miles per hour.  This is a rate:

       r  =  34

We are asked how few he has traveled.  This is a distance.  We use the d=rt equation:

       d  =  rt

           =  (34)(1/2)

           =  17

Markus lives 17 miles from work.

Now try one by yourself.  If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

Can someone answer this question and give an explanation
Temka [501]

Answer:

48cm^2

Step-by-step explanation:

First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.

After that, all you need to do it multiply and then add.

4*9 is 36, and 6*2 is 12.

36+12=48

Hope this helped!
