Draw an isosceles triangle ABC with a base 7 cm long and shoulders 5.5 cm long. Assemble all the heights, measure them, and calculate their sum.

Correct answer:

s =  15.0421 cm

Step-by-step explanation:

a=7 cm r=5.5 cm  v1=r2(a/2)2=5.52(7/2)2=3 2 cm4.2426 cm  S=2a v1=27 4.242614.8492 cm2 S = 2r v2  v2=2 S/r=2 14.8492/5.55.3997 cm  v3=v2=5.39975.3997 cm s=v1+v2+v3=4.2426+5.3997+5.3997=15.0421 cm
