1.
a) [tex]x^{2} +y^{2} = z^{2}[/tex]
b) [tex]n^{2} + m^{2} = o^{2}[/tex]
c) [tex]a^{2} + c^{2} = b^{2}[/tex]
d) [tex]x^{2} + w^{2} = p^{2}[/tex]
2.
a) [tex]a^{2}[/tex]+[tex]9^{2}[/tex]=[tex]15^{2}[/tex]
[tex]a^{2}[/tex]+ 81= 225
[tex]a^{2}[/tex]= 225-81
[tex]a^{2}[/tex]=144
a= [tex]\sqrt{144}[/tex]
a= 12
