Question

set up an equation and solve in an isosceles triangle , the base angels are equal . the vertex angel is 70o . find the base angels of the triangel.

Answer 1

Answer:Let the base angles be

′

x

′

Therefore,

x+x+70

∘

=180

∘

[Given]

2x=180

−70

∘

2x=110

∘

x=55

∘

Hence,

The base angles of the triangle are 55

∘

,

Step-by-step explanation:

Answer 2

Answer:

The answer is 110 degree

Step-by-step explanation:

We know that the sum of all angles is 180 in any triangle

And we know the vertex angle ( 70 degree)

So we simply subtract 70 from 180 to get 110( the sum of both angles )

And if you want the measure individually of each base angle then divide the answer by 2 to which( we get each individual angle )the answer, 55 degree

There fore the answers==

Sum = 110 degree

each individual= 55 degree
