Answer 1

Answer:

aaàaaaa I don't know so sorry

Answer 2

In context to question asked,

We have to determine that, the angles given in question forming a triangle or not.

As per question,

The three angles of triangles are 60º, 70º, 80º respectively.

As we know that,

Sum of all the interior angles of triangle is 180º

So adding the value of angles given in the question,

We will get,

Sum of all the given angles will be $60^0+70^0+80^0 = 210^0$

As the sum of all angles are 210 degree.

So, it will not be possible that, the given angles can form a triangle.

Hence, a triangle with angles 60º, 70º, 80º can't form a triangle.
