Sorry this took so long, hope this helps

also the "a^2" is meant to mean this " $a^{2}$ "

Step-by-step explanation:

1) a^2+b^2=c^2

4^2+3^2=c^2

16+9=c^2

25=c^2

$\sqrt{25}$ =c

5=c

2) a^2+b^2=c^2

15^2+8^2=c^2

225+64=c^2

289=c^2

$\sqrt{225$ =c

15=c

3)a^2+b^2=c^2

10^2+50^2=c^2

100+2500=c^2

2600=c^2

$\sqrt{2600}$ =c

50.99≈c

4) a= $\sqrt{c^2-b^2}$

a= $\sqrt{15^2-12^2$

a= $\sqrt{225-144}$

a= $\sqrt{81}$

a=9
