Question

in an iscosceles triangle , the vertex angle is twice either base angle . ( let the base angle be b in degrees . Remember that the sum of angle of a triangle is 180 degrees )​

Answer 1

Answer:Here is ur answer

Step-by-step explanation:

Sum of bases angles are 2b

According to question,

Vertex angle=2 * base angle

Therefore, vertex angle 2b

Now, 2b+2b= 180°[sum of interior angle of triangle is 180°]

Or,4b=180

Or,b=180/4

Or,b=45°

Hence, value of b=45°
