Find the area of an equilateral triangle with a side of 6 inches.

Mathematics

sweet-ann [11.9K]3 years ago
6 0

Answer:

9\sqrt{3} in²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = \frac{s^2\sqrt{3} }{4} ( s is the length of a side )

Here s = 6, thus

A = \frac{6^2\sqrt{3} }{4} = \frac{36\sqrt{3} }{4} = 9\sqrt{3} in²

Help me with this one problem please :( <br> Find the following arc measures.
r-ruslan [8.4K]

Answer:

Arc KL =23

Arc OM =113

Step-by-step explanation:

We know that Angle NPM is equal to 90 degrees.

Therefore, Angle KPM is also equal to 90 degrees.

We are told that Arc LM is equal to 67.

Thus, the measure for Arc KL is equal to 90-67=23

We also know that Angle OPN is equal to Angle KPL.

Therefore, the measure of Arc ON=23

Using that information, we know that Arc OM is equal to 90+23=113

Hope I helped!

How do I know if two ratios are equal to make a proportion
AfilCa [17]
One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

-7,-12,-17,-22,-27 find the nth term
Bess [88]

Answer:

-2 - 5n

Step-by-step explanation:

-7, -12, -17, -22, -27.....

Arithmetic Sequence

first term a = -7

difference = d = -12 - (-7) = -12 + 7 =  (-5)

nth term = a + (n-1)d

              =  -7 + (n-1)*(-5)

              = -7 + (-5)*n -1 * (-5)

             = -7 - 5n + 5

            = -2 - 5n

Please Find the distance between the two points rounding to the nearest tenth (if necessary).
Sphinxa [80]

Answer:

10.29 u

Step-by-step explanation:

<u>Given :- </u>

  • Two points (7,4) and (-2,9) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

:\implies D = √{(x2-x1)² + (y2-y1)²}

:\implies D =√[ (7+2)² +(9-4)²]

:\implies D =√[ 9² +5²]

:\implies D =√[ 81 +25]

:\implies D = 10.29

<h3>Hence the distance between the two points is 10.29 units .</h3>
