Question

In an isosceles triangle, the base angles are equal. The vertex angle is 80⁰. What are the base angles of the triangle?​

Answer 1

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:

the Base angle is 50°

Step-by-step explanation:

180-80=100

100=2x

100/2=x

50=x
