b^2 = 169- 49 = b = square root of b^2

what did you get?

  • jakyfraze
I'm sorry, i really don't understand this at all :(
triciaal
  • triciaal
you are not reading
triciaal
  • triciaal
now that you have read the response what is b?
jakyfraze
  • jakyfraze
why 169 - 49?

@triciaal and i got 2cm. am i doing something wrong? please help me
triciaal
  • triciaal
what is 169 take away 49 169 minus 49 = 169 - 49 =

120

  • triciaal
so b^2 = 120 to get b take the square root
jakyfraze
  • jakyfraze
@triciaal I'm sorry what do you mean?
jakyfraze
  • jakyfraze
take the square root?
triciaal
  • triciaal
I hope you see the importance of reading and following directions
jakyfraze
  • jakyfraze
so it's 2cm?
jakyfraze
  • jakyfraze
i I'm reading the direction. it's just i don't understand
triciaal
  • triciaal
are you mixing questions or something? how on earth do you get 2cm not even an option

@triciaal i got 120 but you said so b^2 = 120 to get b take the square root. so i got lost :( sorry
triciaal
  • triciaal
that example is showing how to use pythagorean theorem in that example the sides are 3 and 4 so the missing length was the hypotenuse 5 cm in your problem you have the hypotenuse and one leg so you subtract to find the other leg

think of square root as the opposite operation to square just like addition with subtraction and multiplication with division

what was the last bottom part of the picture?
triciaal
  • triciaal
are you understanding now?
jakyfraze
  • jakyfraze
a little bit, please don't get mad I'm now learning this
triciaal
  • triciaal
had computer problems guess that was a sign not to post what I wrote bottom line is I don't get mad when a person needs time. I am extremely patient. I don't appreciate people who say " i don't understand" when they are not trying or reading.
jakyfraze
  • jakyfraze
@triciaal is it B. 120
triciaal
  • triciaal
square root of 120 yes
triciaal
  • triciaal
to review do you understand pythagorean theorem? do you understand the operations square and square root? do you have any other questions?
jakyfraze
  • jakyfraze
@triciaal thank you. were can i go to learn this more. do you know any websites i can go to?
triciaal
  • triciaal
sorry I don't know the best sites (I learnt this before the computer age) but khan academy and yah math have helpful videos.
triciaal
  • triciaal
Math is fun. I think the key is to practice problems so you know the steps to follow and how to identify different theorems etc.
