Question

In on isosceles triangle the base angles are equal the vertex angles is 40 what are the base angles of the triangle remember the sum of three angles of a triangle is 180​

Answer 1

Answer:

ANSWER

Let the base angles be ′x′

Therefore, 

x+x+40∘=180∘                                  [Given]

2x=180∘−40∘

2x=140∘

x=70∘

Hence, 

The base angles of the triangle are 70∘,70∘.

Answer 2

Answer:

70°

Step-by-step explanation:

Given vertex angle=40°

let base angles be x

40°+x+x=180° (angle sum property)

40°+2x=180°

2x=140°

x=70°

Therefore, the base angles of isosceles triangle is 70°
