Question

a=10, b=24. find c. (diagram in comment below)

***fan & medal***

Answer 1

this is pythagoras' theorem

\[a^2 + b^2 = c^2\]

so make the substitutions for find c^2

then take the square root of the answer.

Answer 2

how do i solve it? @campbell_st

Answer 3

ok... so you have

\[10^2 + 24^2 = c^2\]

can you calculate the left hand side of the equation...?

Answer 4

c=26,-26 @campbell_st

Answer 5

well not quite

\[100 + 576 = c^2\]

so

\[676 = c^2\]

now take the square root of both sides to find c

hope it helps

Answer 6

oopps... just re-read you answer... you're correct... you don't need -26 as you as dealing with measurement in this question, and you can't have -26 units of measurement.

well done
