Do line segments with the given lengths form a right triangle? State whether the line segments with the given lengths form a rig
Dvinal [7]

Given:

19, 180, 181

To be able to determine if the given lengths form a right triangle, the following condition must be met:

\text{ a}^2\text{ + }b^2=c^2

Let's check.

a.) At a = 19, b = 180, c = 181

\begin{gathered} \text{ a}^2\text{ + }b^2=c^2 \\ (19)^2+(180)^2=(181)^2 \\ 361\text{ + 32,400 = 32,761} \\ 32,761\text{ = 32,761} \end{gathered}

Therefore, the given lengths could form a right triangle at a = 19, b = 180 and c = 181.

The answer is yes.

It just happened to be that we got the right answer on the first try, you must also examine at a = 180, b = 181, c = 19 and a = 181, b = 19, c = 180 if the first try didn't meet the right condition.

If you failed to get, then the given lengths could not form a right triangle. The answer would be no.

What is the quotient of 6,484 ÷ 24?<br><br> 270 R 4<br> 270 R 8<br> 285 R 4<br> 285 R 8
olga55 [171]

Answer:

Hence, the quotient is 270 and remainder is 4.

Step-by-step explanation:

Let R denotes the remainder after dividing.

We are asked to find the quotient when 6,484 is divided by 24.

On dividing the number 6,484 by long division method we will see that the dividend is not divisible completely that is it is not a factor of 24.

i.e. (6484)÷24=270.16666.

Hence we are also left with a remainder.

The quotient on solving the problem is 270.

and the remainder is 4.

Also in other way we could see that when 6484 is subtracted by the remainder and then divided by 24 then it is completely divisible i.e. we get remainder to be zero i.e.

(6484-4)÷24=(6480)÷24= 270.
