Answer 2

$\huge \red{answer}$

$\large \green{answer \: is \: c}$

$\bold{by \: using \: pythagorus \: therum}$

$h {}^{2} = b {}^{2} + p {}^{2} = h {}^{2} \\ \\ h {}^{2} = 30 {}^{2} + 40 {}^{2} \\ \\ h {}^{2} = 900 + 1600$

$h = \sqrt{2500} = 50m \:$

$\bold{now \: h \: = distance \: from \: a \: to \: c \: } \\ \\ \bold{50 - 12 = 38}$
