Answer 1

Answer:

2)

${x}^{2} = {15}^{2} + {20}^{2}$

${x}^{2} = 225 + 400 \\ {x}^{2} = 625 \\ x = 25$

3)

${y}^{2} = {8}^{2} + {15}^{2} \\ {y}^{2} = 64 + 225 \\ {y}^{2} = 289 \\ y = 17$

4)

${y}^{2} = {12}^{2} + {16}^{2} \\ {y}^{2} = 144 + 256 \\ {y}^{2} = 400 \\ y = 20$

Answer 2

Answer:

2)

${x}^{2} = {20}^{2} + {15}^{2}$

${x}^{2} = 400 + 225$

${x}^{2} = 625$

$x = \sqrt{625}$

$x = 25$

3)

${y}^{2} = {15}^{2} + {8}^{2}$

${y}^{2} = 225 + 64$

${y}^{2} = 289$

$y = \sqrt{289}$

$y = 17$

4)

${y}^{2} = {16}^{2} + {12}^{2}$

${y }^{2} = 256 + 144$

${y}^{2} = 400$

$y = \sqrt{400}$

$y = 20$
