Question

ayudaaaaa por favorrrr :(((

Answer 1

Explicación paso a paso:

d) 15^2 = 12^2 + x^2

225 = 144 + x^2

81 = x^2

√81 = x

9 = x

e) x^2= 20^2 + 15^2

x^2 = 400 + 225

x = √625

x = 25

f) 30^2= 18^2 + x^2

900 = 324 + x^2

900 - 324 = x^2

√576 = x

24 = x

g) 20^2 = 16^2 + x^2

400 = 256 + x^2

√144 = x

12 = x
