Jordan measures the side lengths of a triangular piece of sheet metal. The side lengths are 156 cm, 133cm, and 205 cm. Verify th

Alexxx [7]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the triangular piece of sheet metal is a right triangle, then the side lengths must satisfy the Pythagorean Theorem

so

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

where

c is the hypotenuse (the greater side)

a and b are the legs of triangle

we have

$c=205\ cm\\a=156\ cm\\b=133\ cm$

substitute

$205^2=156^2+133^2$

$42,025=24,336+17,689$

$42,025=42,025$ ----> is true

so

The side lengths satisfy the Pythagorean Theorem

therefore

The triangular piece of sheet metal is a right triangle

X^2 = 1/100, what is x

Contact [7]

X in (-oo:+oo)

X^2 = 1/100 // - 1/100

X^2-(1/100) = 0

X^2-1/100 = 0

1*X^2 = 1/100 // : 1

X^2 = 1/100

X^2 = 1/100 // ^ 1/2

abs(X) = 1/10

X = 1/10 or X = -1/10

X in { 1/10, -1/10 }

Adam and.his dad share the cost of the meal in the ratio of 2:3 adams dad pays 52.50 what is the to cost of the meal?

larisa86 [58]

Adam pays for 2/5 of the meal so his father pays for 3/5

3/5 = 52.50
1/5 = 52.50 / 3 = 17.50

so cost of the meal = 5 * 17.50 = $87.50
