Answer 2

Answer:

It could be an isoceles triangle or scalene triangle.

For Isoceles triangle:

we know that, sum of all the angles of a triangle = 180°

> so, If we talk about an isoceles triangle

x + x + 120° = 180°

2x + 120° = 180°

2x = 180° - 120° = 60°

x = 60° / 2 = 30°

Hence, the type of triangle can be Isoceles.

For Scalene triangle:

> here, all we have to do is,

that as we observed in the isoceles triangle, we got the angles as 30°, 30° and 120°.

now we can make some possible angles

if we subtract 10 from 30 (keeping 120 constant)

we get 20 and on the other we will add 10 to 30 so that we get 40.

Both of these angles are directly proportional to each other. So make sure to balance them and check them by adding all three angles, if you get 180° it's correct but if not then try to follow the steps again.
