Which of the following sets of sides does not form a right triangle?

Mathematics
1 answer:
kolezko [41]3 years ago
3 0

Answer:

7, 24, 26

Step-by-step explanation:

6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)

Different shapes are drawn on cards and then the cards are placed in a bag. The number of cards for each shape is shown in the t
Anvisha [2.4K]
We can first add up the cards so we know how many we have in all:
16 + 16 + 18 = 50 cards

We can do this a little bit easier if we get the "16"-cards in one number total.

16 + 16 = 32

\frac{32}{50} = 32 x 2 = \frac{64}{100}
                                         50 x 2 

\frac{64}{100} = 64 : 2 = 32 %
                                            100
We did just divide the % of two types cards on 2, so we get the %-chance of 1 type card.

I am not quite sure, but I think that 32 % is the correct answer.
