For a triangle with the length of its sides of 5/36, 1/3 and 13/36, determine if it is a right triangle?

Anuta_ua [19.1K]

Yes it is. Input the numbers into the pythagorean theorem,

${a}^{2} + {b}^{2} = {c}^{2}$

and if they equal each other it is a right triangle.

The value of the expression 16 -3/4 is ______.

Korvikt [17]

16-3/4=15 1/4

You can convert to fractions first, and then convert back to a mixed number like:

16/1-3/4 and when you add/subtract fractions you need a common denominator

64/4-3/4

61/4

15 1/4

Or you can convert your fraction to a decimal to get:

16-0.75

15.25
