Question

In an isosceles triangle the vertex angle is twice the base angle .if the base angle be m dergee ,form an equation to find the angle of triangle.

Answer 1

Step-by-step explanation:

isosceles triangle means 2angels are equal

then

• a triangle measures 180°
• ie,bace angel x + x and vertex angle 2x
• ie,x+x+2x=180°
• then 3x=180°/3
• then x=60°
• then vertex angle 2x=60x2=120°bace angels are 60°

Don't mind for the bad drawing
