Answer :
Answer:
The greatest number of acute angle a triangle can contain are:
3
Step-by-step explanation:
We know that a acute angle is a angle whose measure is less than 90°.
Now we know that the sum of all the angles of a triangle is 180°.
Now we have to find such 3 angles which are less than 90° and add up to 180°.
Let we consider a equilateral triangle.
In a equilateral triangle each angle measures 60°<90°.
and also:
60+60+60=180°.
Hence, the greatest number of acute angles a triangle can contain are:
3.
