Mathematics
1 answer:
lakkis [162]4 years ago
7 0

Answer:

6

Step-by-step explanation:

All of the triangles are similar, so the ratio of hypotenuse to short side is the same for all.

... x/4 = 9/x . . . . that ratio for smallest and largest triangles

... x^2 = 36 . . . . multiply by 4x

... x = 6 . . . . . . . take the square root

What is the anwser to the problem
torisob [31]

8 ) 712

8 goes into 71 8 times; the product of 8 and 8 is 64.

Subtracting this 64 from 71, we get 7, to which we append 2: 8 ) 72.

8 divides evenly into 72: 9.

Thus, the desired quotient is 89.

Which of the following sets of sides does not form a right triangle?
kolezko [41]

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 :)
