All dogs are warm-blooded.
All warm-blooded creatures are mammals.
Hence, all dogs are mammals.

A. True
B. False

The sentence, "Hence, all dogs are mammals," is a premise in this argument.

Option 'A' is true.

Step-by-step explanation:

Since  we have given that

All dogs are warm blooded.

It means Dogs ⇒ Warm blooded (1)

and

All warm blooded creatures are mammals.

Warm blooded ⇒ mammals (2)

So,  from Eq(1) and Eq(2), we get that

Dogs ⇒ mammals

⇒ All dogs are mammals.

Hence, Option 'A' is true.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
