Question

In an isosceles triangle the vertex angle is thrice either of base angle. Let base angle be b in degrees

Whoever answers best with explanation step by step will be marked as brainliest answer.​

Answer 1

Step-by-step explanation:

Let the base angle =b

⇒vertex angle =2b

Sum of angles in a triangle =180°

⇒b+b+2b=180

⇒b=45°

Angles =(45°,45°,90°)
