Find the height and area of the equilateral triangle ​
sergejj [24]

As here we are given with an equilateral triangle, whose side is 3 cm, and we need to find the height and area of the equilateral triangle. So, for this let's recall that, the area of any equilateral triangle with side a is given by ;

  • {\boxed{\bf{Area_{(Equilateral\:\: Triangle)}=\dfrac{\sqrt{3}}{4}a^{2}}}}

So, if we substitute a = 3, in our Formula, it will yield to

{:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(3)^{2}}

{:\implies \quad \sf Area_{(Equilateral\:\:Triangle)}=\dfrac{\sqrt{3}}{4}(9)}

{:\implies \quad \boxed{\bf{Area_{(Equilateral\:\:Triangle)}=\dfrac{9\sqrt{3}}{4}\:\:cm^{2}}}}

Now, as we know that, for any triangle we also have a formula that is ;

  • {\boxed{\bf{Area_{(Triangle)}=\dfrac{1}{2}\times Base\times Height}}}

Now, Here as the triangle is equilateral, so it's base will just be same 3, and if we let height be H, so we will be having

{:\implies \quad \sf \dfrac{1}{2}\times 3\times H=\dfrac{9\sqrt{3}}{4}}

{:\implies \quad \sf H=\dfrac{9\sqrt{3}}{4}\times \dfrac23}

{:\implies \quad \boxed{\bf{Height=\dfrac{3\sqrt{3}}{2}\:\:cm}}}

There are 22 animals in the barn. Some are ducks and some are oxen. There are 72 legs in all.
xeze [42]

Answer:

  • 14 oxen
  • 8 ducks

Step-by-step explanation:

Let x represent the number of oxen. Then the number of ducks is 22-x and the number of legs is ...

  4x +2(22 -x) = 72

  2x +44 = 72 . . . . . . . simplify

  x +22 = 36 . . . . . . divide by 2

  x = 14 . . . . . . . . . subtract 22; the number of oxen

  22-x = 8 . . . . . the number of ducks

There are 8 ducks and 14 oxen in the barn.
