campbell_st · Answer

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.

how do i solve it? @campbell_st

campbell_st · Answer

ok... so you have 

$$10^2 + 24^2 = c^2$$

can you calculate the left hand side of the equation...?

anonymous · Answer

c=26,-26 @campbell_st

campbell_st · Answer

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

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
