Answer:
1.41a
Step-by-step explanation:
Let ABC is a right triangle with equal legs AB =BC.
Hence, ∠B is 90° and CA is the hypotenuse.
Now, applying Pythagoras Theorem, we can write
CA² = AB² + BC²
Let us assume that each legs AB = BC = a.
Therefore, CA² = a² +a² = 2a²
⇒Hypotenuse or CA = a√2 = 1.41a { Round to the nearest tenth} (Answer)

Answer:
(b) tan B = 8/6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Then angle B is involved in tangent and cosine relationships this way:
tan B = 8/6 . . . . . . matches 2nd choice
cos B = 6/10 . . . . . matches no choices

<em>Additional comment</em>
Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
Start with the bottom surface area, 7x7=49
then go to the triangles, base times height divided by 2, so (7x14)/2=49
and since there are 4 triangles, multiply 49 by 4 = 196 and add the area of the bottom, which all adds up to 245
