If two angles of a triangle are 10 degrees and 20 degrees, then the triangle is?

an obtuse triangle im pretty sure

The given triangle is obtuse angled triangle.

Step-by-step explanation:

Given,

Two angles of a triangle are 10° and 20°

To find the type of triangle

We know that the sum of the three angles of a triangle is 180°

So, 3rd angle is 180° - (10°+20°)

= 150°

Hence, the triangle is obtuse angled triangle.
