Right triangle = Pythagoras theorem.
a^2+b^2=c^2
there's already c and b so
10^2-8^2=a^2
100-64= 36
a^2=36
square root both sides
to get 6.

$Angles$ $that$ $form$ $a$ $linear$ $pair$ $add$ $up$ $to$ $180 degrees$ .

If the measure of angle 1 is 113, then all we must do is subtract:

180-113=67 $degrees$

And we're done!

Good luck! :)

Hope it helps you!
