Hey there!!

How do we solve this problem :

We will use the combinations formula to solve this :

c ( n , r ) where n = 11 and r = 2

c ( n , r ) =  n ! / r ! ( n - r ) !

... 11 ! / 2 ! ( 11 - 2 ) !

... 11! / 2! × 9!

... 11! / 2 × 9!

... 11×10×9×8×7×6×5×4×3×2 / 2×9×8×7×6×5×4×3×2

... 11×10 / 2

... 11 × 5

... 55 combinations.

Hence, the required answer = 55 , option ( d )

Hope my answer helps!

Which set of numbers can represent the side lengths in cm of a right triangle HURRY
nikdorinn [45]

Answer:

B.

Step-by-step explanation:

When finding the lengths of a right triangle, use the Pythagorean Theorem. That's a²+b² = c². C is the hypotenuse, which is always the longest side. So, when you plug in the numbers to work it out, it would be 10²+24² = 26². 10² = 100. 24² = 576. 26² = 676. So, your final equation would be 100+576 = 676. 100 added to 576 is 676, which makes this equation true. Therefore, you know that 10, 24, and 26 are the correct lengths of the right triangle.

I don’t get how to find the base the height the side and the length
iren2701 [21]

Answer:

Well, the best way to think about it is base=bottom and then the height is the middle dotted line. The side lengths are the two sides of the triangle, not including the bottom.  The two side lengths are 13 and the height is 12. I hope this helped a bit, if not then just let me know.
