Question

In an isosceles triangle , the vertex angle is twice either base angle ( let the base angle be b in degrees) . Form an equation​

Answer 1

Answer:

Step-by-step explanation: Image result for In an isosceles triangle , the vertex angle is twice either base angle ( let the base angle be b in degrees) . Form an equation

Since the sum of the interior angles of any triangle adds up to 180∘ and also the base angles of an isosceles triangle are equal,we may let the base angles be x , then the vertex angle is 2x . ∴x+x+2x=180∘

Answer 2

Answer:

180°

Step-by-step explanation:

Since the sum of the interior angles of any triangle adds up to 180∘ and also the base angles of an isosceles triangle are equal,we may let the base angles be x , then the vertex angle is 2x . ∴x+x+2x=180∘ .
