Question

ex:1 Plss! Dau coroana

Answer 1

a) MN || BC => teorema lui Thales =>
AM/MB = AN/NC => 2/14 = 3/NC => NC = 21
AB = AM + MB = 16
AC = AN + NC = 24
b) MN || BC => teorema lui Thales =>
AB/MB = AC/NC => 12,5/MB = 7/5 =>
MB = 8,92
AM = AB-MB = 3,58
AN = AC + NC = 2
c) MN || BC => teorema lui Thales =>
AM/MB = AN/NC => 2√3/3√2 =
=AN/√6 => AN = 24
AB = AM + MB =7,7
AC = AN + NC = 6,4
