A triangles angles add up to 180 degrees.
So if you have 24 degrees + 36 degrees = 60 degrees

180 degrees - 60 degrees = 120 degrees

So x = 120 degrees.

Obtuse triangles - 1 obtuse angle (greater then 90 degrees)
Acute triangles - have all 3 acute angles. (Less then 90 degrees)
Right triangle - has 1 90 degree angle.

So, in this triangle, it fits under the Obtuse triangle because there is 1 obtuse angle.

Conclusion: x = 120 degrees. The triangle is an obtuse triangle.
