ha ha i never knew that, is my solution right? · 2 years, 11 months ago

lol I got no idea I never tried. whenever it's nontraditional mathematics on Brilliant I never give it a go (even though I could solve 90% of the problems if I invested the time) because it's most likely too time consuming for no good reason. Btw I liked Madara way better. now you put this stupid pikachu on lol... not hating on pokemon, but I love Madara. btw don't tell me anything from manga or episodes - I'm like 10 episodes behind.

thx and yeah if you wanna fix a typo - your own or someone else's - use the star before the word like

Mardokay: *you're

CBD and CAE are similar. Therefore, BC/CA=BD/AE. Thus BD=2.5 units. Area of CBD=BC.BD/2. Answer is 6.25 unit square · 2 years, 11 months ago

6.25 as 5\20=bd\10 then we can find bd = 5\2 the area = .5 × (5\2 )× 5=25\4=6.25 unite^2 · 2 years, 11 months ago

$$6.25 unit^2$$ · 2 years, 11 months ago

How please explain. · 2 years, 11 months ago
