Answer 2

Answer:

(i)AB=

$\sqrt{(15 - 19) {}^{2} + (11 - 3) {}^{2} }$

$\sqrt{ ( - 4) {}^{2} + (8) {}^{2} }$

$\sqrt{16 + 64}$

$\sqrt{80} = 4 \sqrt{5} \: ans$

(ii)AB=

$\sqrt{( - 5 - 17) {}^{2} + (1 - ( - 4)) {}^{2} }$

$\sqrt{( - 22) {}^{2} + (5) {}^{2} } = \sqrt{484 + 25}$

$\sqrt{509 \: ans}$
