FG = 16
Step-by-step explanation:
Two pairs of consecutive are congruent so, its a kite,
Opposite sides are equal in kite so,
x + 11 = 3x + 1
or, 11 - 1 = 3x - x
or, 2x = 10
so, x = 5
FG = x + 11 = 5 + 11 = 16
Answer:
y = 80
Step-by-step explanation:
the angles of a triangle = 180. the top angle is 80 and the bottom is 20. 180 - 20 - 80 = 80
It the multiplication property because you are multiplying 2x=20 so then you divide on both sides with 2 and that gives you 10
Answer:
600
