No, it never can be a right triangle. 

First, all the angles of an equilateral triangle is 60 degrees because all angles are the same and all the angles add up to 180:

180/3 = 60.

So if it is a right angle it needs one angle 90 degrees which an equilateral triangle can't have,

No, because a equilateral triangle has all even sides and a right triangle has no equal sides. There for a equilateral triangle can not be equal to a right triangle.

Giovanna used the calculations below to determine the height of a stack of 7 books that are each 2 and StartFraction 5 over 8 En
igor_vitrenko [27]

The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)

<h3>Fraction</h3>

Her calculation:

  • 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)

  • 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)

  • 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8

  • 14 and StartFraction 5 over 8 EndFraction: 14 5/8

Her error was multiplying 7 by 2 and adding with 5/8(step 3)

Correct calculation:

7(2 + 5/8)

= 14 + 35/8

= (112+35) /8

= 147/8

= 18 3/8
