Question

1.-b=18
c=25 Formula:
a=? a²+b²=c²
2.-a=6
c=10
b=?

Answer 1

Respuesta:

$1. \: a = \sqrt{301} \: \: \: \: \: \: 2. \: b =8$

Explicación paso a paso:

$1. \: {a}^{2} + {b}^{2} + = {c}^{2} \: \\ {a}^{2} + {18}^{2} = {25}^{2} \\ {a}^{2} + 324 = 625 \\ {a}^{2} = 625 - 324 \\ {a}^{2} = 301 \\ a = \sqrt{301}$

$2. \: {a}^{2} + {b}^{2} = {c}^{2} \\ {6}^{2} + {b}^{2} = {10}^{2} \\ 36 + {b }^{2} = 100 \\ {b}^{2} = 100 - 36 \\ {b}^{2} = 64 \\ b = \sqrt{64} = 8$
