Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
1. x=24
2. b) 15ft, 39ft, 36 ft.
Working out for 1)
[tex] {25}^{2} - {7}^{2} = 576 \: and \: \sqrt{576} = \: 24[/tex]
Working out for 2)
[tex]{15}^{2} + {36}^{2} = 1521 \: and \: \sqrt{1521} = \: 39[/tex]
