What type of triangle has side lengths 2, √12, and √19?

Is an scalene obtuse triangle

Step-by-step explanation:

step 1

Find the type of triangle by the measure of the interior angles

we know that

If applying the Pythagoras Theorem

----> we have a right triangle

----> we have an obtuse triangle

----> we have an acute triangle

where

c is the greater side

we have

substitute

so

----->

we have an obtuse triangle

step 2

Find the type of triangle by the measure of the sides

we have that

The measure of its three sides is different

therefore

Is an scalene triangle

a)(x-2)^2+(y-1)^2=9
