Answer 1

Scalene and Acute

Explanation:

We know that,

A scalene triangle is a triangle whose none of the sides are equal in measure.

A triangle is acute if all of it's angle measure below 90 degree.

Here,

The sides of the given triangle are 12.1,11,10 and 12.1≠11≠10, due to which the triangle is scalene.

All the angles of the given triangle are 51,59,70 and 51,59,70<90, Hence, the given triangle is acute
