(a) You're correct it is 6, because of \(a^2+b^2=c^2, a^2+8^2=10^2, a^2=10^2-8^2, a^2=6^2, a=6.\)

 

(b) \(a^2+b^2=c^2, a^2+24^2=25^2, a^2=25^2-24^2, a^2=25+24, a^2=49, a=7.\)

 

(c) \(a^2+b^2=c^2, a^2+8^2=17^2, a^2=17^2-8^2, a^2=225, a=15.\)

 

(d) \(a^2+b^=c^2, a^2+15^2=25^2, a^2=25^2-15^2, a^2=400, a=20.\)
