Question

I really need help on this geometry question, please, and thank you.

Answer 1

250

Explanation:

you have to use the fact that the big triangle and the small triangle are similar and write the proportions

`(125)/(10) =(AB)/(10)` we took half of the side because of ΔABD and ΔBD..

AB= (125*10)/10=125

is AB =125 then AC is duble AC= 2*125=250
