Answer:
Step-by-step explanation:
Since surface area consists of the sum of the outer faces of each polygon, the ratio of the two surface areas will be equal to the ratio of the side lengths squared (since we multiply them to get area).
The ratio of the corresponding side lengths of the solids are . Therefore, the ratio of their surface areas must be
Answer:
35/12
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the tangent ratio is ...
Tan = Opposite/Adjacent
Applying this to the given triangle, we see ...
tan(B) = AC/BC
tan(B) = 35/12
