Answer:

The triangle is not a right triangle

[tex](\theta)[/tex] is an acute angle

[tex]cos(\theta) > 0[/tex]

Step-by-step explanation:

we know that

If a²+b²>c²

then

Is an acute triangle

therefore

angle theta must be less than 90 degrees

Hence

The triangle is not a right triangle

[tex]cos(\theta) > 0[/tex]

[tex](\theta)[/tex] ---> is an acute angle
