Best ResponseYou've already chosen the best response.110 is the longest side, so we add those 2 I think

Best ResponseYou've already chosen the best response.3you have 2 right angle triangles of which oyu know 2 sides Use Pythagoras to work out the 3rd side of each

Best ResponseYou've already chosen the best response.3@Epicteatime please stop there .. it is not adding or subtracting....

Best ResponseYou've already chosen the best response.3dw:1434376275460:dw use Pythagoras to find a and b then add them to get th eanswer

Best ResponseYou've already chosen the best response.1a^2 + b^2 = c^2 I can never figure out where I plug in the numbers though

Best ResponseYou've already chosen the best response.3c is always the longest side but don't confuse a and b in YOUR equation with those in my diag take each triangle: dw:1434376491882:dw dw:1434376528838:dw

Best ResponseYou've already chosen the best response.1So its a^2 + 6.5^2 = 7.5^2 in the first one and the second one is a^2 + 6.5^2 = 10?

MrNood

Best ResponseYou've already chosen the best response.3yes (I assume you mean 10^2 in th second)

Best ResponseYou've already chosen the best response.1So then its a + 42.25 = 56.25 and a + 42.25 = 100

Best ResponseYou've already chosen the best response.3yes  so get the 2 different values for a  and add them together

Best ResponseYou've already chosen the best response.3sorry NO you have missed out the a SQUARED in your formula

Best ResponseYou've already chosen the best response.1ok, um what do I square?

MrNood

Best ResponseYou've already chosen the best response.3So then its a^2 + 42.25 = 56.25 and a^2 + 42.25 = 100 so you need to solve for a^2 then take sqrt to find a

Best ResponseYou've already chosen the best response.1So do I subtract 42.25 from 56.25 and 42.25 from 100 and square the answer?

MrNood

Best ResponseYou've already chosen the best response.3almost but you sqrt the answer (not square it)

Best ResponseYou've already chosen the best response.3a^2 + 42.25 = 56.25 a^2 = 56.2542.25 a = sqrt(14)

MrNood

Best ResponseYou've already chosen the best response.3and do the same for the other equation a^2 + 42.25 = 100 a=?

Best ResponseYou've already chosen the best response.1isn't 100 42.25= 57.75?

MrNood

Best ResponseYou've already chosen the best response.3a^2 + 42.25 = 56.25 a^2 = 56.2542.25 a = sqrt(14) use the same method....... a^2 + 42.25 = 100 a=?

Best ResponseYou've already chosen the best response.1a^2 + 42.25 = 100 a^2 = 100  42.25 a= sqrt (57.75)

Best ResponseYou've already chosen the best response.3ok  that's correct so now add the 2 separate values for a to get length AC

Best ResponseYou've already chosen the best response.1So 3.74 + 7.59 = 11.33
