Answer:
Sorry this took so long, hope this helps
also the "a^2" is meant to mean this "[tex]a^{2}[/tex] "
Step-by-step explanation:
1) a^2+b^2=c^2
4^2+3^2=c^2
16+9=c^2
25=c^2
[tex]\sqrt{25}[/tex]=c
5=c
2) a^2+b^2=c^2
15^2+8^2=c^2
225+64=c^2
289=c^2
[tex]\sqrt{225[/tex]=c
15=c
3)a^2+b^2=c^2
10^2+50^2=c^2
100+2500=c^2
2600=c^2
[tex]\sqrt{2600}[/tex]=c
50.99≈c
4) a= [tex]\sqrt{c^2-b^2}[/tex]
a=[tex]\sqrt{15^2-12^2[/tex]
a=[tex]\sqrt{225-144}[/tex]
a=[tex]\sqrt{81}[/tex]
a=9
