The triangle is acute. Since all triangles have 180 degrees, you can find the third angle by subtracting the sum of the other angles from 180.
180 - (25 + 87) = third angle
180 - 112 = third angle
68 = third angle
Since all three angles are less than 90 degrees, it is an acute triangle.

The triangle is am acute triangle because angles 25°, 87°, and 68° are less than 90° it means all angles are acute angle, so the triangle is an acute triangle.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have a triangle in which the measures of the angles given below:

Let's denote a first angle with a second angle with b:

a = 25° and

b = 87°

We know in the triangle, the sum of the all angles is 180°

Let's suppose the third angle is c, then

a+b+c = 180°

25°+87°+c = 180°

112 + c = 180°

c = 68°      (subtract by 112 on both sides)

As we can see the angles 25°, 87°, and 68° are less than 90° it means all angles are acute angle, so the triangle is an acute triangle.

Thus, the triangle is am acute triangle because angles 25°, 87°, and 68° are less than 90° it means all angles are acute angle, so the triangle is an acute triangle.
