Answer:
Scalene and Acute
Step-by-step 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
