Question

me pueden ayudar a resolverlo

Answer 1

a)

${5}^{2} + {x}^{2} = {30 }^{2} \\ 25 + {x}^{2} = 900 \\ {x}^{2} = 875 \\ x = 5 \sqrt{35}$

b)

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

c)

${6}^{2} + {x}^{2} = {10}^{2} \\ 36 + {x}^{2} = 100 \\ x = 8$

d)

${24}^{2} + {x}^{2} = {25}^{2} \\ 576 + {x}^{2} = 625 \\ x = 7$
