Question

Qa) In a right angle triangle where angle A=98 and AB=ACwhat are the values of angles b and c ​

Answer 1

Answer:

B=45 DEGREE        C=45 DEGREE

Step-by-step explanation:

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  

+2∠B=180  

 

2∠B=180  –90  

=90  

 

⇒∠B=45  

 So, ∠C=∠B=45
