Question

ABC is a right angle triangle at B and AB:BC=3:2 . Which is the least angle​

Answer 1

Answer:

Since AB=AC,  

So, △ABC is Right-angled isosceles.

∠B=∠C             ...(angles opp. to equal sides are equal)

∠A+∠B+∠C=180  

∘

       ...(angle - sum property of a triangle)

Substituting ∠B=∠C, ∠A=90  

o

 

90  

∘

+2∠B=180  

∘

 

2∠B=180  

∘

–90  

∘

=90  

∘

 

⇒∠B=45  

∘

 

So, ∠C=∠B=45  

o

.
