Answer:

Step-by-step explanation:

To determine if the given values are part of a right-angled triangle, we need to use the Pythagorean theorem, removing one of the variables, and if it results in the neglected value, it is a right-angled triangle.

a^2+b^2=c^2\\

b.

21^2+24^2=c^2\\c=31.9

DEF is not a right triangle.

c.

7.1^2+2.4^2=c^2\\c=7.5

GHI is a right triangle.

Mekhanik [1.2K]

Answer:

label a graph doing -5,-8, and 4,4  use the formula which is

d = ( x 2 − x 1 )^2 + ( y 2 − y 1 )^2

 x2-x1 = 4–2= 2 Y2–Y1 = 1–3 = -2 d=√(2)^2+(-2)^2 =√4+4 = √8 d= 2√2

so this is the same thing the person above me did but I've been typing this out so long I want to go ahead and submit anyway

valentinak56 [21]

1st piece = x

2nd piece = x+2

3rd piece = x+2+3 = x+5

37 = x +x+2 + x+5 =

37 = 3x+7

30=3x

x = 30/3 = 10

 1st piece = 10 inches

 2nd piece = 10+2 = 12 inches

 3rd piece = 10+5 = 15 inches
