2a.
Since BC = 10m and M is the midpoint, we can find CM by : 10÷2 = 5m
So, CM = 5m

2b. Now, you have the base ( 5m) & hypotenuse (13m). Pythagoras' Theorem:

c {}^{2}  =  {a}^{2}  +  {b}^{2}
Where c is the hypotenuse, a & b are sides.

{13}^{2}  =  {5}^{2}  + b {}^{2}  \\  {5}^{2}  +  {b}^{2}  = 13 {}^{2}  \\  {b}^{2}  = 13 {}^{2}  -  {5}^{2}  \\ b =  \sqrt{144}  \\ b = 12
b here refers to the height.

2c.
Area of a right-angled triangle =
\frac{base \times height}{2}
So,
\frac{10 \times 12}{2} \\  = 60 {m}^{2}

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-8}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{-8}{4}\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-2}(x-\stackrel{x_1}{2})\implies y=-2x+4
