Question

The vertical angle is an isosceles traingle is 80degree. Find measurment of its base angles.​​

Answer 1

Answer:

50°,50°

Step-by-step explanation:

let base angle be x

in a triangle

x+x+80=180( base angles in a isosceles triangle are equal )

2x=100°

x=50°

Answer 2

Answer:

The base angles of the triangle are 50∘

,50∘

Step-by-step explanation:

Let the base angles be ′ x ′

Therefore,

X + X + 80∘ = 180 [Given]

2x = 180 ∘ − 80∘

2x = 100∘

x = 50∘

Hence,

The base angles of the triangle are 50∘

,50∘
