Answer:

The length of the three sides 5, \sqrt{58} , \sqrt{65}

The triangle <u>is not</u> a right triangle

Step-by-step explanation:

A = (3, 2) , B = ( 6, 9) , C = (10, 6)

Find the lengths using distance formula.

distance = \sqrt{(x_2 -x_1)^2 + (y_2 - y_1)^2}

AB = \sqrt{(6-3)^2 + (9-2)^2}  = \sqrt{9 + 49 } = \sqrt{58}

BC = \sqrt{(10-6)^2 + (6-9)^2}  = \sqrt{16 + 9}  = \sqrt{25}  = 5

AC = \sqrt{(3-10)^2+(2-6)^2}  = \sqrt{49 + 16} = \sqrt{65}

Using Pythagoras theorem :

(Longer \ side)^2 = sum \ of \ square \ of \ two \ other \ sides

Longest side is AC . So we will check if it satisfies Pythagoras theorem :

\sqrt{65} = \sqrt{58} + 5^2\\65 = 58 + 25\\

65 ≠ 58 + 25

So the sides does not satisfy Pythagoras theorem. Hence the triangle is not a right triangle.

Multiple of two has a 50 percent chance. greater than 15 is 25 percent. if both it's 10 percent

I have two fair dice, each numbered 1 to 6. I add the two numbers together. What is the probability that I get a total of 5
Lostsunrise [7]

Answer:

Each dice has six combinations which are independent. Therefore the number of possible outcomes will be 6*6 = 36. The probability of rolling a pair of dice whose numbers add to 5 is 4/36 = 1/9.

Step-by-step explanation:

For the odds of these two numbers coming up at the same time, you multiply the odds of one times the odds of the other. 5/6 × 1/6 = 5/36. So the odds that you'll roll 2 dice total six are 5/36 each time you roll ( or approximately 1 chance in 7).
