Answer:
Figure 1: x = 120°
Figure 2: x = 54°
Figure 3: x = 64°
Step-by-step explanation:
Every triangles interior angles will add up to 180°
Figure 1: 30 + 30 + x = 180
60 + x = 180
x = 120
Figure 2: 104 + 22 + x = 180
126 + x = 180
x = 54
Figure 3:
part 1: 154 + z = 180
z = 26
part 2: 90 + 26 + x = 180
116 + x = 180
x = 64
