Atriangle has side lengths of 6, 8, and 9. what type of triangle is it? equiangular acute right obtuse

The given triangle is an acute angle triangle.

Step-by-step explanation:

In a triangle if three sides are given as 6, 8, and 9 then we have to find the type of triangle.

As we know for equiangular triangle

all sides should be equal therefore the given triangle is not an equiangular triangle.

For an acute angle triangle

a²+ b² > c²

6² + 8² = 10²

which is > 9²

Therefore it's an acute angle triangle.

For an Obtuse angle triangle

c²/2 < a² + b²< c²

9²/2 < 6² + 8² < 9²

81/2 < 100 < 81

This inequality is wrong.

Therefore the given triangle is an acute angle triangle.

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
