Answer 1

1. x=24

2. b) 15ft, 39ft, 36 ft.

Explanation:

Working out for 1)

`{25}^(2) - {7}^(2) = 576 \: and \: √(576) = \: 24`

Working out for 2)

`{15}^(2) + {36}^(2) = 1521 \: and \: √(1521) = \: 39`

Answer 2

1. 24

2. B

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
