Find the length of the hypotenuse, c , for the right triangle with sides, a = 7 and b = 7 . round to the nearest hundredth.

In any right triangle with sides a,b and hypotenuse c, the pythagorean theorem states that

So, we have

Which means that

If you ask any calculator, you'll get something like

So, since the thousandth digit is a 9, the approximation to the nearest hundredth is 9.90.

step- i d k and i d c : )

you: : 0

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
