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

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

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

The side lengths satisfy the Pythagorean Theorem

therefore

The triangular piece of sheet metal is a right triangle

What’s the sum of the numbers 1 to 100

seropon [69]

Remark

You can use a formula to get the right answer. Otherwise you will use a lot of paper adding 100 numbers together.

Givens

A = 1

L = 100

n = 100 numbers to be added together. There are 100 numbers between 1 and 100 numbers inclusive.

Formula

Sum = (A + L)*n/2

Solution

Sum = (1 + 100)*100/2 Substitute in the givens. Add what is inside the brackets

Sum = (101) * 100 / 2 Divide by 2

Sum = 101* 50 Multiply

Sum = 5050 Answer
