Question

What is the length of FG, where FG is parallel to side BC ?​

Answer 1

Step-by-step explanation:

as IN TBC, TC=TB=BC=12M

so, angle T, B, C are 60 degree

but G is midpoint of TC so, TG=6 cm

F is midpoint of TB so, TF=6 cm

As angle A is 60 degree and TF and TG are equal so angle F, G are equal and 2x+60=180

x=60

so that TFG IS a equilateral triangle that's why TF=FG=GT=6 m
