Question

plz help question no.. 6 very very urgent

Answer 1

ANSWER.






GIVEN



AB=12m


BC=5m








FORMULA USED



Pythagoras therom


In right triangle ABC






${ac}^{2} = {bc}^{2} + {ab}^{2}$






${ac}^{2} = {12}^{2} + {5}^{2}$







${ac}^{2} = 144 + 25$








${ac}^{2} = 169$






$ac = \sqrt{169}$






$ac = \sqrt{13 \times 13}$



$ac = 13m$



HENCE

FULL. LENGTH OF TREE= BC+AC



BC=5m. (given)

AC=13m. (just prove)



so


Full length of tree before broken= 5+13

=18m
