Answer 1

Answer:

Explanation:

Sheep have 32 permanent teeth with a dental formula of 2 (incisors 0/4, premolars 3/3, and molars 3/3). The temporary incisor teeth erupt sequentially at approximately weekly intervals from birth.

Answer 2

Answer:

We know that in a △, the sum of all the interior angles is 180  

∘

 

⇒∠A+∠B+∠C=180  

∘

Also given that,

∠C=3∠B and 3∠B=2∠A+2∠B

∠A=  

2

∠B

​  

 

Substituting values in (1), we get

2

∠B

​  

+∠B+3∠B=180  

∘

 

∴∠B=40  

∘

 

   ∠A=20  

∘

 

   ∠C=120
