Question

suppose a triangle has sides a,b, and c, and that a²+b²>c². Let theta be the measure of the angle opposite the side of length of C​

Answer 1

Answer:

The triangle is not a right triangle

$(\theta)$ is an acute angle

$cos(\theta) > 0$

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

$cos(\theta) > 0$

$(\theta)$ ---> is an acute angle
