I am a triangle with the following angle measures. Find the missing angle measure and describe the triangle by the sides and angles

angle 1 = 35 degrees

angle 2 = 110 degrees

angle 3 =

Can there be more than one obtuse angle in a triangle? Why or why not?

No. Each triangle must equal 180 degrees. An obtuse triangle is more than 90 degrees so if we had two obtuse angles (let's say they measure 91 degrees each), that would make the triangle over 180.
