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.

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
