So to start:The equation you want to use for the hypotenuse isA (squared) + B (squared) = C (squared)So you will want to fill in the equation, as well:7(7) + 4(4) = C (squared)So now that you have your information complete, to put it all together!49 + 16 = 65Now don't forget that 65 years is raised to the SQUARE!You will want to use the SQUARE ROOT method to help with that!So what you want to do, is to think of the numbers that are PERFECT SQUARES.A perfect square consist ofHere is the list of perfect squares 1-10:1 x 1 = 12 x 2 = 43 x 3 = 94 x 4 = 165 x 5 = 256 x 6 = 367 x 7 = 498 x-8 = 649 x 9 = 81So look closely at these perfect squares, do you see where 65 lie?Located between the 8 and the 9.So you will have to take the square root now.√65The answer will be:8.06225775 will Be rounded to the nearest tenths place (one place after the decimal point)You will see the two digits behind the decimal point that is0.6.As you know,(If you round to the tenths place), if the number of hundredths is 5 or HIGHER. Will round the number in the tenths place 1. As well as we know that 6 is greater than 5 so your answer would be:8.1 I hope this helped! :)>^.^<( )~
