Answer:
z = 120º
Step-by-step explanation:
t + 2t + t + 2t = 360º
60 + 2(60) + 60 + 2(60) = 360
t = 60
2t = z
z = 120º
This is all based on the fact there there are 360º in a quadrilateral.
This is not a right triangle as 2.6 squared plus 8.1 squared does not equal 8.6 squared (Pythagorean theorem)

Answer:
x = 2 m
y = 30°
Step-by-step explanation:
The side lengths of ΔDEF are 3/9 = 1/3 of those of ΔABC.
x = DF = 1/3(AB) = (1/3)(6 m)
x = 2 m
__
Angle measures of ΔDEF are the same as those of the corresponding angles of ΔABC.
y = ∠B = ∠E = 30°
y = 30°
