Answer:
1. 4^2+3^2=5^2
16+9=25
[tex]\sqrt{25}[/tex]=5
2. a=17.5
3.c=25
Step-by-step explanation:
2. explanation
a^2+b^2=c^2
With this the equation we have to use is this-
c^2+b^2=a^2
So-
15^2+9^2=a^2
(15*15)+(9*9)=(a*a)
225+81=a^2
306=a^2
[tex]\sqrt{x}[/tex] means finding the number times itself equals 306
[tex]\sqrt{306}[/tex]=17.492≈17.5
a=17.5
3. explanation
7^2+24^2=c^2
49+576=c^2
625=c^2
[tex]\sqrt{625}[/tex]=25
c=25
