Bahaha I don’t remember my shapes at all I asked for teachers help and she grabbed my paper and told the whole class to be careful with problem 4 and said some of you are not reading the directions:0

Step-by-step explanation:
since, the sum of all the angles of a triangle is 180
and here all angles are congruent, so x=y=z
so, x +y+z =180°
3x = 180°
x =60°
so angle x =y=z = 60°
this is the answer
