Step-by-step explanation:
Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.
Since they do not have all 3 congruent angles, they are not similar.
Now THAT's a problem !
Lemme at it ! Outa my way !
The probability of picking two of the friends to work together is
(the number of pairs of friends there are)
divided by
(the total number of pairs that can be pulled out of 21 students).
The number of pairs of friends there are is (3 x 2) / 2 = 3 pairs.
The total number of pairs that can be selected out of 21 students is
(21 x 20) / 2 = 210 pairs.
The probability that the pair selected will be two of the friends is
3 / 210 = 1/70 = about 1.43 % (rounded)
Sorry I need a picture to answer sorry :c
The steps to this problem would be first simplifying 9e^6 x-2+7=45 to 9e^6x+5.Which translates into 9e^6 x+5=45.
Then Subtract 5 from both sides : 9e^6 x = 45 - 5Now simplify 45-5 to 40
9e^6 x = 40
Now divide both sides by 9:
e^6 x = 40/9
Then divide both sides by e^6
x = 40/9/e^6
And finally simplify that into x = 40/9e^6. That's your final answer. Comment if you need more help or for me to explain more. Hope this helped :)
