PLEASEEEEEE HELP <br> Given: △ABC, D∈AC<br> m∠BDC=m∠ABC<br> AD=7, DC=9<br> Find: BC, BD/BA
Sergio [31]

Answer:

Step-by-step explanation:

Given: △ABC, D∈AC , m∠BDC=m∠ABC , AD=7, DC=9.

Solution: Let BC=x, From the given figure and the given information, it can be seen that △ABC is similar to ΔBDC by AA rule, thus using the proportionality theorem, we get

\frac{AC}{BC}=\frac{BC}{DC}

⇒\frac{16}{x}=\frac{x}{9}

⇒x^{2}=144

⇒x=12

⇒BC=12

Now, calculate the similarity scale,

k=\frac{AC}{BC}

=\frac{16}{12}=\frac{4}{3}

Therefore, \frac{BA}{BD}=\frac{4}{3}

⇒3BA=4BD

⇒BA=\frac{4}{3}BD

Can somebody help me with this it a little hard
vova2212 [387]

The answer to your question is,

A. 7 large buckets and 3 small buckets.

So, a large bucket has 25 that can fit and a small fits 13. Take 214 and divide it by 25. You'd get a decimal number. 8.56. You see, you can't overfill the 8th bucket by another clam, so you would have to downsize it to where the crabs would fit, so that means 8 buckets. Alongside the rest goes into the small buckets.
