oh so 15^2+4^2=c^2? :)
well... c = 15... so.... |dw:1389310826385:dw|
\(\bf c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b\)
oh so 15^2+4^2+b^2? thanks :) im gonna try to work it out now
do i do square root over 15^2-2^2 together on my caculator or make them seperate like 15^2=225 and 4^2=16?
depends on the calculator really if it's just a buttons one... then .... no graphic.... then ...hmm you'd get the 15[square button] - 4[square button] then the root button
oh okay yeah your right. ill just square them seperate. i got 225 and 16
thanks for the link :)
I got 14.45? o.o
ooops... is 15... one sec dohh, I used 5 =)
hahaha its okay. so thats the answer??
yeap
