Step-by-step explanation:

a. Obtuse Scalene Triangle. It has one angle that is greater than 90 degrees and have two equal sides so it's a obtuse scalene triangle.

b. A triangle interior add up to 180 degrees. We are given the upper angle which is 173. The other two angles must add to 180 but must be equal.

x + y + z = 180

y = z

x + z + z = 180

x + 2z = 180

x=173 so

173 + 2z = 180

2z = 7

z = 3.5

3.5 degrees.
