BC=7 cm
Step-by-step explanation:
1.Triangle BCD an isosceles triangle
2. To Find BE ?
3. CD =40 cm
4. BC =29 cm
5.As BE is the median it bisects the base into two equal parts As CD is is the base it gets bisected =20cm.
6.so in Triangle BCE By PT THM BE =7 cm
7.so I have found BE =7 cm
8. If any problem tell me mate

no I solved the answer is 21 and it was asked to find BE not BC by the PT THM it is 21
check question Bro I am correct
I have found BE only
You will understand now with diagram
no actually my dad is expert in maths but he was not available that time so i post this over here and then asked dad so he solved it for me and that was the answer but thanks for your try !
I saw your diagram and it is correct but the answer isn't
see I will tell you 20×20= 400 29×29=841 841-400=441 = 21
